My first encounter with Jenny Colgan and it was enjoyable. She writes tight science fiction with great characterizations and ideas. Clearly, she did some research for the book and this made it more interesting. If you are interested in mathematics, or at least those who profess to be mathematicians, you may enjoy some of the characters even more.

Some interesting twists and the book could have been a lot more detailed and philosophical but it was kept tight and action based. Great one day read. Could be an enticing little movie and easily developed into a series.

From Goodreads – Connie thinks she’s never met anyone quite like Luke Beith before.

She has no idea how right she is.

As a high-ranking mathematician in a male-dominated field – with bright red hair – Connie’s used to being considered a little unusual.

But she’s nowhere near as peculiar as Luke, who is recruited to work alongside her on a top-secret code-breaking project.

Just what is this bizarre sequence they’re studying? It isn’t a solution to the global energy crisis. It isn’t a new wavelength to sell microwave ovens. The numbers are trying to tell them something . . . and it seems only Luke knows what.

The truth is out there. Will Connie dare to find it?

In this whirlwind adventure, Sunday Times bestselling author Jenny Colgan boldly goes where no author has gone before . . .
