Proving his innocence may cost him his life...

After a brutal attack, US Marshal Riker Kastell regains consciousness only to find a murdered gang member in his mudroom. Even worse, Eliana Daines — his ex-sweetheart — has a DNA program that pinpoints him as the murderer. And Eliana’s technology has them both targeted by criminals. Now he and his K-9 must protect Eliana...and find the killer who looks just like Riker before they become the next victims.
