The Black Room by Gillian Cross

4.0

Fast paced and exciting sequel! Robert is big again, and he's trying to help the little people in the cavern at the park. With the help of his (at first disbelieving) friend Tom and sister Emma, they formulate a plan to help the little people through the winter. Meanwhile, Lorn (the defacto leader, since Zak and Cam are still gone) is working on her own plan to expand the cavern. But above ground, Tom and Robert have discovered that the real "Lorn" is in danger, and set out to liberate her from her family and reunite big and little. Lorn is more mature than seems possible for her age and circumstances, but if you can suspend the big/little disbelief, you can accept her role in this story.
