Matthew Cost is finished with Crimson Thaw: Brock Justice is a flawed and damaged cop straddling the thin blue line of loyalty and doing the right thing. "Crimson Thaw" immerses the reader in the area of Maine from Downeast to Bangor to Augusta, or the real Maine. The suspense is razor sharp, the action is breathless, the plot is twisty, and the characters are as real as they get. Check it out.
