I need to read the rest of this...and soon!

I love Holly Seddon, her first two books have been brilliant and this one looks to be as good. It spans over years with the main characters lives being looked at as both adults and children and I'm guessing it will be the fallout from the events of their childhoods that will affect their adulthood. Holly Seddon writes engrossing and exciting books with great plotlines and characters that you either hate or fall in love with....I'm intrigued to see which of these the main characters fall into for me. I'malready hppked after 27 pages.....surely that's the sign of a great book?! How will their childhood impact on their childrens childhood? What is the twist going to be in this book? I need to read it all....and soon!!
