American Monsters was written by Derek Landy and first published in 2016. It follows the continuing adventures of Amber and Milo as they try to find a way to finally stop Amber’s twisted parents. The book forms the final instalment of The Demon Road Trilogy, and is preceded by Demon Road (2015) and Desolation (2016). I’d strongly advise that you read the books in sequence if you want to have any idea of what’s going on.
Amber is struggling to come to terms with her new role as the Shining Demon’s representative on Earth. She’s stronger than ever, her demonic side fuelled by vials of her benefactor’s blood, but using these is starting to come at the cost of her sanity. And then there are the things she must do – things that enable serial killers to go on killing. She knows that she needs to find a way to break her contract before she completely loses her soul.
And then there is the problem of her parents. Bill and Betty are still on the run and know that they’re living on borrowed time. When Amber finally catches up with them, they cut a deal. They know that they won’t live long while the Shining Demon is still in power. They want Amber to deliver the monster to them so that they can devour him and take his place. If Amber can do that, they promise that they’ll leave her alone to live her life.
Amber knows that her parents can’t be trusted, but there is one small problem. They’ve taken Kelly hostage and will kill her if Amber doesn’t deliver the goods within six days. With Kelly’s life on the line, Amber and Milo have no choice but to hit the road to find chains powerful enough to bind a Lord of Hell. However on the way they will encounter many old friends and enemies and, now that it’s known that Amber is the Shining Demon’s lapdog, it’s difficult to know who they can trust…
