I love all of Jackson Pearce's fairy re-tellings because the covers are always so artistic and so amazing that you can't help but want to open the book and read it. :) 
 Sweetly is a retelling of the Hansel and Gretel fairy tale and it was as equally enjoyable as Sisters Red. In this one, Gretchen is a tough character as well, who is trying to cope with the disappearance of her twin sister as well as her family falling apart. Her toughness isn't the same as the sisters from the first novel; her strength comes more from the insider of her, her emotional and mental strength. There is a sort of continuation from the first novel, as the Fenris from book 1 make a reappearance here. 
 Sweetly started out really good, with a mystery on how and why girls are always disappearing after Sophie Kelly's annual chocolate festival. As the story progresses, I felt that the mystery was slowly solving itself because of all the little clues that was planted, but don't get me wrong. There are still elements of the book that keeps you interested, such as Gretchen's friendship with outcast Samuel, as well as Ansel's budding romance with Sophia Kelly. 
 This time around, we have more of a story that develops the character and emotions. While there is still action, I preferred the emotional depth that was featured instead. The ending was a little unexpected, but I think it worked out really well. I'm quite excited for book #3, since it'd be dealing with mermaids! Yay!
