Metamorphosis is the perfect ending to the Hell Bent/Heaven Sent novelette series by Isobel Lucas.
I wasn't sure what Lucas had planned after I finished the fourth installment, Infliction, but it certainly wasn't this. (That's a good thing, by the way.) Lucas takes readers on a roller coaster ride from the beginning, all the way through to the end.
The pacing is fantastic. The character development is superb (especially with Raven, aka Mary). I devoured this installment, and while I loved how Lucas ended this series, I'm sad to see it come to an end. I really came to adore both Raven and Ian.
As with her work as Megg Jensen, I will eagerly be awaiting her next release!
