Another great book from Suzanne Wright. I am still loyal to The Phoenix Pack and favor them, but really enjoyed reading, Spiral of Need, book 1 from The Mercury Pack series. I really liked seeing the Phoenix Pack members crossed over into this book. Hopefully we will continue to see them throughout the rest of this series. 
 I couldn't put Spiral of Need down. It was great from beginning to end. The character development was perfect. The relationship building on point. The feelings palpable between the pack members and the mates. The action scenes were exciting and had my pulse quickening and me pacing. The sex scenes were hot. Overall, this was a complete win. 5 stars. I can't wait for the next book to come out.
