I really liked the book in general. The couple is amazing together despite their age difference or the way they've met.
That said, I hate to admit that I can't give it more than three stars.
The whole "daddy/blankie-sucking" thing (ok, cocksucking too, but still, the boy constantly feels a strong urge for sucking his Daddy's tits) messes with my head. I wish Angel was more of an 18-year old and less of a baby.
There is also this: How can a mature person, an experienced Dom on top of it, leave someone helpless, locked in a cage, not for an hour or two, while grocery shopping (which is still unforgivable), but for a prolonged period of time? O.o
