Good plot with multiple story threads adding complexity to the characters and their relationships. Plus the the plot thickens! Book 2 had the best mystery, but BtS is focused on the character and preparing for book 4, the series conclusion. Binding the Shadows ends with a cliffhanger. It's going to change motivations, add higher stakes, and I'm anxious to read how Bennet will resolve everything.
Next up: Banishing the Dark (book 4 and final book)
Out-of-print! Very expensive mass paperback - $19 Amazon only! Used books cost from $9 (my ordered copy) - $138+. If you see this book at a used book store, get it! If you have it, keep it!
