Jacquelyn Frank's "Nightwalkers" series continues with Noah, the King of the Demons, a character who's been rather sketchy in previous books (Jacob, Gideon, Elijah, Damien) but who now gets a story to himself. As with the other books in this series, the central plot involves Noah finding his fated mate, in this case a rather unusual human named Kestra. Noah, as King, is dedicated to protecting his people from their enemies both human and Nightwalker, but he is beginning to fear his own nature - as Samhain approaches, a time when some demons lose control, he worries that this will happen to him. It doesn't help that he's been dreaming of a mystery woman for the last six months - he doesn't know her name or anything about her, but he can't get her out of his mind.

When Noah discovers that he has been dreaming of his imprinted mate, a woman who knows nothing about him, he sets about finding her. But things aren't going to go smoothly for Noah; he may find he's too late to reach her. Even if he does find her, she may not want to become part of his life - and what if she's been too damaged by events in her past to feel comfortable with him?

Although not that much actually happens in Jacquelyn Frank's books, somehow they don't drag. We spend a great deal of time following conversations between Noah and Kestra as well as other characters whom we've met in previous books. The 'goodies' have to fight against the 'baddies' in Noah, but that's a fairly minor part of the overarching story; we focus much more on the relationship between Noah and Kestra. While Kestra isn't a particularly appealing character and Noah, too, has his off moments, overall this is a reasonably continuation of this series, giving several insights into the ongoing stories of some of the heroes and heroines from previous books.

Noah is significantly longer than its predecessors at over 500 pages but seems less imbued with an actual plot than the fourth book (Damien). Still, it's a reasonable read for paranormal romance fans.
