Deranged Specter - Street Games, #4

All bets are off. After all she's been through, nothing will stop Kyra from finding her brother. Kyra has a new disguise--a new charade--that may prove infinitely more dangerous. She now stalks the Mire with gangsters and thugs, dodging a serial killer and searching. Always searching... Gabe searches for Kyra relentlessly, but she has once again disappeared into the darkness of the Mire. Meanwhile the serial killer still haunts Gabe's jurisdiction, the Prowlers are an ever-growing threat, and the mystery of Gabe's brother's disappearance seems to have gone cold.
But Abstreuse City never remains quiet for long. Oh no. There's a great deal of darkness in store for Kyra and Gabe. If only they can find the strength to meet and overcome it. Join them on a pulse-pounding run through the bowels of Abstreuse City, where demons of the past and future are about to collide.
