Large PB, no creasing, but you can tell it has been read. Happy to combine postage.

Grace Lisa Vandenburg counts. The letters in her name (19). The steps she takes every morning to the local café (920). The number of poppy seeds on her orange cake, which dictates the number of bites she'll take to eat it. Grace counts everything, because that way there are no unpleasant surprises.

Seamus Joseph O'Reilly (also a 19) thinks she might be better off without the counting. If she could hold down a job, say. Or open her cupboards without conducting an inventory, or leave her flat without measuring the walls.

Grace's problem is that Seamus doesn't count. Her other problem is . . . he does.

As Grace struggles to balance a new relationship with old habits, to find a way to change while staying true to herself, she realises that nothing is more chaotic than love.
