The Theory of (Not Quite) Everything by Kara Gnodde is a heartfelt, intelligent and uplifting novel about true love in all its forms . . .

Bound together by their parents’ tragic death, devoted siblings Mimi and Art have different ideas about everything – most recently, how Mimi should find love.

Art, a maths genius, believes people are incapable of making sensible decisions, especially when it comes to romance. That’s what algorithms are for. But Mimi is sure that love is more than just a numbers game.

So, when Mimi meets the charismatic Frank seemingly spontaneously, Art starts looking for a glitch. Because something doesn't add up, and Art fears he's in danger of losing his sister forever . . .
