In mathematics, recursion is the definition of a sequence through self reference, for example, the Fibonacci sequence. Blake Crouch has sci-fi in the bag. 

At first, I didn’t understand the two POV’s. Helena, the creator of “the chair”, a device that (accidentally) can take a person back in time to themselves at a specific moment where they had a strong emotional reaction, made sense. Barry, the detective who lost his 16 yr old daughter 10 yrs prior in an accident, did not (at first). Crouch was a genius in how he brought the two timelines together. I love how he implemented ideas of time, space, memory and quantum physics using recursion as the overarching idea. 

I even enjoyed the romance aspect of the novel and how the characters found each other, recursion after recursion and fell in love almost every single time. AND it didn’t feel like a disaster romance where the characters only fell in love because of circumstances or proximity.

My only issue with Recursion is the same problem I had with Dark Matter. The pacing felt off to me. The beginning felt so slow and I had trouble locking in and focusing on the story until I was about 60% of the way through the novel.

Mr. Crouch has gained a forever reader in me because I’ve loved both of the novels I’ve read of his and I can’t wait to see what topics he tackles next.
