This is great start to the Intangible Series. You get your first peak at Jonas here and see how he functions in the present time. You also get get quite the look at him when he was human.
I'm honestly surprised Jonas feels as he does toward humans after all he'd been through in his life. A lesser being would have been lost forever, yet Jonas somehow found his way back.
The Realm is described in such vivid detail you can almost smell the air there if you try hard enough.
Lilith, while we all know she's the mother of all vampires. I have to ask what happened to the first she sired. The rumors buzz about Jonas being Lilith's chyld like it's a shock, yet how are all the others that follow her there if they weren't sired by her. Surely there must have been one or more Jonas that was sired by Lilith to make the rest. As early as 50 years prior to Jonas since Adrian had only been turned 50 year before they meet.
Regardless of whether or not you're a fan of the series, or like me, just discovering it? You'll fall in love from the first sentence.
