Weighing the Scales - Dragonsigns, #2

No one man can stop him. A madman with invisibility armor. A girl clinging to life. Her brother will make any bargain to protect her. Even Colin mastering his own shapeshifting magic armor hasn't been enough to keep his sister out of the hospital. Eric's coming to take her back, with armor that gains power with everyone he kills. With the police hunting them all, Colin risks everything by trusting a crafty lieutenant who may have his own agenda.
But Eric has allies of his own, as he draws closer to the final secret that could make him invincible. A monster at Colin's front, and knives at his back. Which way can he turn? Weighing the Scales is the second book of the thrilling Dragonsigns urban fantasy series. If you like pulse-pounding action, back-alley mystery, and Jim Butcher's Dresden Files, this is the book to grab.
