Penalty Box Valentines, a sapphic roller derby romance concept package. The graphic shows 4 novel covers and the free lead magnet, Lace Me In First.

The concept

Maz Cabrera knows exactly how it feels when Corinne puts her on the floor. She’s less sure what to do when Corinne takes her hand after practice and holds on. Their rival leagues have to share a track, and a play that used to be a dare is suddenly an act of trust.

On the same oval, a substitute opens her locker to a gift from a secret admirer, two childhood friends stretch their last lap past midnight, and a retiring captain gets another chance with the woman who got tired of coming second to derby. The free prequel starts at the fitting bench, where Jo has been waiting years for Etta to lace up again.

The worldTwo adult, skater-owned flat-track leagues share practice space, then form a combined travel squad. A jammer scores points by passing opponents. A pivot can take the jammer’s star mid-jam. The bout callers, substitutes and skaters all have lives after the hall empties.
Series tropesSports Romance • Slow Burn • Flirtatious Teasing Banter
Intended readershipFor readers who want adult sapphic sports romance, competitive women with different bodies and ambitions, and attraction you can see in the way two skaters move together.
Tone & contentPlayful and physical with moderate open-door intimacy. All central couples are adult women. Sports injuries receive ordinary recovery time.

Free novella

Lace Me In First

Etta has been lending out her old skates for so long that everybody assumes she has retired. Jo notices that Etta still oils the bearings. When a Sunday open skate needs one more adult demonstrator, Jo offers to rebuild the boots over four Friday nights. Etta can cope with badly behaved wheels. It’s the end of each fitting, when Jo takes her hands off Etta’s ankles, that is getting difficult.

Story outline
Story arc and endingJo leaves the rebuilt skates at Etta’s flat with a takeaway menu and no practice deadline. Etta puts them on to answer the door on their first date. Etta admits that fear of falling has kept her behind the desk. Jo wants an actual date and refuses to make affection a reward for skating. They take one before the demonstration. At open skate Etta falls, laughs and gets herself up while Jo cheers from the bench. Weeks later the two run Sunday fittings together, wear matching keys and welcome the neighbouring league to their floor.
Emotional payoffEtta can accept a tender gesture without turning it into a test. Jo discovers that Etta is quite capable of making the first move.

Kiss on the Pivot Line

Maz keeps a tally of every time Corinne has put her on the floor. Corinne keeps the little notes Maz leaves beside the penalty clock. Neither collection is strictly professional. When two leagues field a combined travel squad, the women have six weeks to learn a star pass together. Maz can flirt her way through most things. Handing Corinne the star means letting the whole hall see exactly how much she trusts her.

Story outline
Story arc and endingThey trade the star during a drill with their eyes closed. Away from the crowd, Corinne admits she keeps every one of Maz’s notes. Corinne likes wanting Maz best when the rivalry gives her cover. They practice in private and begin going out after the hall empties. When Maz turns their first public pass into a joke about Corinne owing her a kiss, Corinne leaves. Maz apologises to her and the squad and lets Corinne choose the next play. Corinne asks her out at the team breakfast. A decisive pass earns the victory, and a season later both still keep score on the fridge in their flat.
Emotional payoffMaz has to recognise the difference between enjoying an audience and volunteering Corinne for one. Corinne chooses the moment when being seen feels like her idea.

Borrow My Wheels

Somebody keeps leaving the perfect wheels in Pip’s cubby. Soft ones for the polished hall, hard ones for the sticky away floor. The unsigned notes are better than most dates. Pip would like to find the writer before she falls for her. Unfortunately the woman she already wants is Sal, the visiting skater with a beautiful mouth and the expensive gear Pip can barely bring herself to touch.

Story outline
Story arc and endingA broken wheel stops Pip during the reserve bout. She borrows a league set, wins a place on the roster and discovers the woman she admires is standing in her cubby holding an unsigned note. Sal confesses to the gifts on their first date. Pip is delighted until she learns Sal has covered her arrears without asking. She returns the money and earns her starting place at open trials using loan equipment. Sal admits how much she misses being wanted when she has nothing to give. They start dates on alternate budgets, and Pip proposes a member-owned lending locker. A year later their matching loan stickers sit on their own shared front door.
Emotional payoffPip’s pride protects a hard-won independence. Sal finds out what Pip wants once the two of them stop communicating through presents.

Jam After Midnight

Lenka knows three reliable things about midnight practice. The floor sticks by the exit, the vending machine owes her six dollars, and Tish always saves her the last dance under the ancient mirror ball. They’ve been friends since they wore plastic skates. When their overnight scrimmage draws its first paying crowd, Lenka realises that Tish has been treating their last lap as a date. Now she has to decide what she wants the lights to come up on.

Story outline
Story arc and endingTish brings Lenka breakfast after dispatch and meets the sister who has heard about every midnight lap. Lenka realises how thoroughly Tish already belongs in her life. Tish asks Lenka to go public as a couple. Lenka wants her family to hear it from her first and resents finding their last lap on a fan’s feed. Tish helps take it down and asks which moments Lenka wants to share. Lenka tells her sister herself, then invites Tish to supper without promising anybody a performance. At the midnight exhibition they leave the hall separately and go home together. At the next season opener Lenka introduces Tish as her wife.
Emotional payoffTish gives up the idea that a public declaration measures love. Lenka takes the risk of naming the relationship to the one person whose opinion matters most.

The Captain Takes a Knee

Dot has been threatening to retire for eleven seasons. This time the notice is on the board, signed in ink. Val, the woman who once begged her to pick a weekend that didn’t belong to derby, comes to collect her old gear. Neither expects to spend the championship teaching their replacements how to take a hit. Dot knows how to leave the track. She has never learned how to ask Val to stay.

Story outline
Story arc and endingThe rookie who inherits Dot’s place fouls out in a warm-up. Val catches Dot reaching for her old helmet and asks whether she wants to skate or just cannot bear to watch. Their old breakup began when Dot promised a last season and secretly signed up again. Val accepts a novice coaching role because she misses derby on her own terms. Dot declines a final-game comeback even when a spot opens, keeping her retirement decision independent of their reunion. Val finds her kneeling to lace a rookie’s skates. She asks Dot to lace hers next, then takes her on the postponed first Sunday away. Their return as a married spectator and a coach closes the series.
Emotional payoffDot learns to support the team from the bench. Val sees her keep a difficult promise before agreeing to build another life with her.
