God, I have... So many feelings about this book.
It might be bold of me to say, but I might love it more than the first one? (That's a lie, I love them both equally.)
Ari and Gwen are absolutely fabulous wives, now and forever, and I absolutely adore the route that Amy Rose and Cori went with the time travel plotline (I suspected where they were going about forty pages in and LOVED IT) and then the mother of all plot twists at the end had me reeling and ready to cry and I was SITTING ON THE EDGE OF MY SEAT FOR THE ENTIRE LATTER PART and god now I just want a third book even though it probably won't happen.
