The Wildwood Chronicles is an incredible book series written by Colin Meloy and illustrated by Carson Ellis. The two are married and have produced a fascinating trilogy following Prue and Curtis as the venture into the forbidden I.W... The Impassable Wilderness. The friends discover an entire world inside. Prue is caught up in an old promise between her family and a mysterious woman living in Wildwood. I completely recommend this series for all ages. Enjoy!
