Going under (first read Under the wood)

  In Under Wildwood Darla Thennis (as the jet black fox) attacks Prue, but curtis and the bandit king saves her. They bring her back to camp. Meanwhile the elder mystic (the leader of the mystics) is killed by Darla and 2 other shape sifting foxes. Prue feels her death (she can hear plants and they were yelling). She soon has a pull pulling her towards North wood with curtis. Once she gets there she hears about how the elder mystic died. Then a boy mystic says "the true heir must be remediated". They go back to the camp to do the quest, but they find out Darla and 3 other jet black foxes destroyed the camp. Some bandits died, others lived and fled. They get attacked by the foxes and fall down the long gap (a ravine, that the bandit camp is on the walls of). They soon wonder into the caves at the bottom of the ravine. They soon find civilization of moles that need help getting back their fortress of fanggg (spelled with 3 gs) from an usurper mole. Can they do it?
  Elsie and Rachel makes friends with a girl named martha. Soon they get suspicious with whats happening with the unadoptables. So they go into office of the person who runs the place (Mr. Unthank). They find boxes that have the initials of all the unadoptables. They steal one, but after stealing are caught and made unadoptable. Mr. Unthank uses his experiments (that are for going into wildwood) on them and sends them into the wood. If they come back it is freedom for them. In the wood they find all the other unadoptables in a house making a family with a old man. Meanwhile Mr. Unthank is asked by a man, to make a complicated machine in 5 days, that lets people go into the wood.
  This book is compelling and mysterious. A part of the book with walking could just turn into the most important part of the book. I recommend this book.
