Mercury with Style - Mercury Hale, #7

Mercury Hale has saved the world. A lot. So, no one can blame him for enjoying time off from the neverending task of slaying astral fiends. For about five seconds. A daylight attack ends with the revelation of a mysterious voice-coming from the very monster he's supposed to destroy. What's a guy to do? Dig into the mystery of secret files he received that point deeper into Procyon Foundation's shadowy history.
Hope he can find a missing operative. And keep up his guard against an insidious new enemy savvy enough to make friends with the old ones. Because the Whisperer isn't the only powerful being with an agenda. And Mercury's not about to let anyone he cares about get caught between them.
