The Blurb

My heart is a kaleidoscope, and when we kiss it makes my world unravel . . .

Gottie H. Oppenheimer is losing time. Literally. When the fabric of the universe around her seaside town begins to fray, she’s hurtled through wormholes to her past and starts to experience strange blips in time…

Back to the day her best friend Thomas moved away and left her behind with a scar on her hand and a black hole in her memory.

Back to last summer, when Gottie’s life fell apart. When her beloved grandfather Grey died and Jason, the boy to whom she lost her heart wouldn’t even hold her hand at the funeral.

This summer, still reeling from twin heartbreaks, Gottie is lost and alone and burying herself in equations. Until, after five years absent, Thomas comes home: former boy next door. Former best friend. Former everything.

As life turns upside down all over again, during one long, hazy summer, Gottie navigates grief, world-stopping kisses and rips in the space-time continuum as she tries to reconcile her first heartbreak with her last. Although Grey is still gone, Jason and Thomas are back, and Gottie’s past, present, and future are about to collide – and someone’s heart is about to be broken.

This is what it means to love someone.

This is what it means to grieve someone. It’s a little bit like a black hole.

It’s a little bit like infinity.

With time travel, quantum physics and sweeping romance, The Square Root of Summer is an exponentially enthralling story about love, loss and trying to figure it all out, from stunning debut UKYA voice Harriet Reuter Hapgood.

The Review

Ok, I won’t lie to you. I was a bit confused by The Square Root of Summer. It was a very good story of a girl dealing with grief but it has a mathematical time travelling twist that I struggled to get my head round. I am just that dumb.

The story focuses on Gottie who is dealing with the death of her beloved granddad, the break-up of her first real relationship and the abandonment of her best friend. Due to this she has become introverted and seems to have also managed to open up some wormholes. She believes that if she can figure out the math of the worm holes maybe she will feel a little less broken.

Reuter Hapgood has written a good story that deals with grief on a different level. At times you get frustrated with the time travel element – or at least I did but then I have issues with time travel in general – especially doing the same thing over and over again. However, it really is a good read.
