"Vampire novels are still totally in, especially this gripping first title from the Relentless series." ~  GL magazine (

"Relentless was so well-written, so well-developed and so fun, exciting and suspenseful that I simply could not put it down. I have to give author Karen Lynch mad props for this book. She has written a book that is absolutely un-put-downable." ~ Reader's Favorite

"Practically overflowing with supernatural beasts, this diverting story is more action tale than teen romance." ~ Kirkus Reviews
