The Mystery of Hollow Places by Rebecca Podos
My rating: 3 of 5 stars
The subject matter is a good one - mental health or, in this case, mental unhealth. Imogene has a dad and stepmom. She also has half of geode and a story about her mother that her father told her. Then one day her father disappears. Imogene believes it is her duty to find him.
The book has a few side stories happening. Some that are pertinent. Others that don't really seem to tie in so well. The basic concept of separating what you know from what you don't, challenging yourself how you know it is true, and above all, appreciating what you do have, are the strongest parts of the book.
