Into the Wild is aimed at grade-schoolers, and the language reads like it. I tend to like my fairy tale remixes to be a little more mature, but taking this for what it's intended as, it's very well done. At first I thought the stories/type characters would stick pretty closely to their origins, but Durst managed some nice twists that left me feeling like she wasn't just rehashing the usual material.
The story is about 12-year-old Julie and her mother, Rapunzel, as well as several other friends who escaped "the Wild" and now live in the real world (such as the flighty "Cindy," selfish "Goldy" and Julie's "brother" Puss in Boots). Until someone breaks into the well at the Wishing Well Motel and makes a wish -- which sets the Wild free to grow and shape their lives again.
In the end I thought it was a nice blend of several stories, with some new ideas. I enjoyed the characters and I think Durst has a nice little package of a story here. Nothing too in depth, but perfect if you're just looking for a light read.
There is a sequel, Out of the Wild, which I haven't checked out yet (but I will). This might be slightly misleading, because the story isn't left hanging with characters in dire straights; however, the possibilities for the sequel are fairly clear.
