Break A Leg: A Queer Novella by Briar Townsend

Lucas Quinn is a successful non-fiction writer living in Brighton with his two beloved dogs. A new neighbor, Matty, moves in next door, piquing the interest of both Lucas and his pets. They're all introduced during a chance encounter and Lucas is instantly charmed.

Matty is shy, Lucas is afraid of scaring them off, and it might take a medical emergency but Fate is determined to give these two their happily ever after.

With the help of Lucas's dogs, codependent friends, and a long night at the A&E, Matty and Lucas might finally find what they've been waiting for.

TLDR: A fluffy, queer romance involving a meet cute, a night in the A&E, and a first date. Queer and genderfluid main characters, as well as an autistic main character. Short and sweet.
