The Theory of (Not Quite) Everything

Meet Art and Mimi Brotherton.
Like circles in a Venn diagram, they have always come as a pair. Siblings. Housemates. Bound together by the tragic death of their parents, they're all the other has. And they agree on not quite everything.

Art thinks that people are incapable of making sensible decisions when it comes to love, including his sister. That's what algorithms are for.

Mimi knows her brother is a mathematical genius, but also knows maths isn't the answer to everything.

With Mimi's unwavering support of Art's brilliant mathematical mind, living together has always been very practical for him, if rather unfulfilling and lonely for her. So when Mimi begins her search for love, Art insists that she use a strict mathematical principle of his own making, alongside a dating algorithm, to help her find her soulmate. The initial results seem promising. That is until Mimi meets Frank: a romantic, spontaneous stargazer, and also a mathematician, he is most definitely not algorithm-approved.

As Art's mistrust of Frank grows, so do Mimi's feelings, and the siblings' relationship is tested to breaking point - for something about Frank doesn't quite add up, and only Art can see it...

In a world where three is an always an odd number, will they be able to will they be able to reconcile their differences and find the answers they're hoping for?

The Theory of (Not Quite) Everything by Kara Gnodde is a tender, intelligent and uplifting novel about brothers and sisters, true love in all its forms, and how the bonds of family and calculations of the heart are determined to follow a logic all of their own.
