** spoiler alert ** 
 This was a spectacular book! It's awesome, I love it soooooooooo much!!!!! It's like when Clary finds out she's a shadow hunter in City of Bones. Oops sorry for another spoiler. I so was engrossed with it. The time traveling is so adventurous and I love stories about the past and the future! I REALLY LOVE that passage where The present Gywneth sees her future self KISSING Gideon! THAT was one juicy future for her! I also think the romance between Gwyneth and Gideon is just beginning. The only let down was that there were parts where it was childish and immature-it kind of bothered me and I thought,"Aren't they all in young adults already?"....so.....it's a 4.50 out of 5
