Although it's VERY well-written, I'd be remiss if I didn't admit that (compared to Everwild) at least 70 to 80 percent of this book is somewhat disappointing. However, it does build up to a downright FANTASTIC (though bittersweet) conclusion for the trilogy. 
 It will tear your heart out. And stomp on it. Don't say I didn't warn you. 
 Recommended.
