 Such a lovely reading! For once: no vampires or angels or werewolves but time travelers wow!! too cool! Add: cute characters, twisted plot but easy-to-read and nice style. I couldn't put this book down. It took me 1 day to read and I had then to rush to the 2nd and 3rd book. I don't know how people managed to wait between one book and the next one.
