If you haven't read the first two books in the series, stop reading now as there will be spoilers for you. Moving on. The events of the previous book have left the crossroads in a strange state, such that every time Rose passes into the twilight, it's some new, strange version of a nightmare, you know, like where the sun is trying to eat her, for example. Not cool at all. But if something is up with the crossroads, then they won't be protecting Bobby anymore and maybe she can kill him, ridding herself and many others once and for all of this murderous scum. Funnily enough, Apple, Queen of the Routewitches, asks Rose to do just that and uses Rose's niece, Bethany, as a carrot. After all, Bethany is also tied to the crossroads, and if something has happened to them, she won't be anchored to the twilight anymore. But first, Rose must get permission from Persephone. After all, she has the Queen of the Dead's favor, as well as her ever-blooming corsage on her wrist and her tattoo on her back, so better to clear it with the goddess first.
Suffice it to say that Angel of the Overpass is one long road trip as Rose does whatever it takes to see that the stars align so Bobby Cross can finally get dead. Especially since he has recently taken to threatening all of those she loves, from Emma at the Last Dance/Last Chance Diner, to Gary, her boyfriend-turned-car, and all the diners and folks she cares about in between. She'll encounter a snotty Dullahan (headless horsewoman) named Pippa, who guards Persephone; she'll meet an angry dinosaur ghost that is an aggregate creation of all the dinosaurs who have turned to crude oil (not pretty!); she'll find herself in a diner filled to the brim with spectral teenagers and truckers who were the victims of an arson-related hate crime and they can't manage to leave; and she'll even encounter an umbramancer who has been luring unsuspecting ghosts to her diner to trap them for years. Oh, and she also bumps into the anima mundi, AKA the soul of the world. Needless to say, the road is long and never boring.
The end of Angel of the Overpass is satisfying and it's clear that this isn't the end of the road for Rose (sorry with the road jokes - stories about road ghosts bring them out in me). I didn't find this installment as intriguing as the previous book, but I was glad to see it play out. If you've been keeping up with the series, you'll want to check this one out and see where Rose is headed next.
