I'd been recommended Holly Black for good urban fantasy and a realistic depiction of kids on the streets, and Valiant definitely delivered.It was hard to get into at first, but before I knew it, I was sucked into the world of kids living beneath the subways in NY who divide their time between dumpster diving, running errands for trolls and faeries and shooting up a faerie medicine that lets them create illusions and convince others to do their will. One of those books that had been compulsively digging it out of my purse whenever I could catch a few minutes to find out what happened next.
