Tilly Twomley is desperate for change. White knuckling her way through high school with flawed executive functioning has left her burnt out and ready to start fresh. A summer internship and the required travel around Europe promises a much-needed change of scenery as she plans for her future. The problem is, Tilly has no idea what she wants.

Oliver Clark knows exactly what he wants. His autism has often made it hard for him to form relationships with others, but his love of colour theory and design allows him to feel deeply connected to the world around him, and he's taking summer internship to build his resume before he starts design school. Everything is going as planned until he suffers through the most disastrous international flight of his life, all turmoil stemming from lively and exasperating Tilly. Oliver is forced to spend the summer with a girl that couldn't be more his opposite - feeling things for her he can't quite name.

As the duo's neurodiverse connection grows, they learn that some of the best parts of life can't be planned and are forced to figure out what that means as their disastrously wonderful summer comes to an end.

Mazey Eddings is a neurodiverse author, dentist, and (most importantly) stage mom to her cats, Yaya and Zadie. She can most often be found reading romance novels under her weighted blanket and asking her boyfriend to bring her snacks. She's made it her personal mission in life to destigmatize mental health issues and write love stories for every brain. With roots in Ohio and North Carolina, she now calls Philadelphia home.
