Silent Trail by Blake Pierce

With a career-ending injury, Olympic kickboxer Sheila Stone is forced back to her small hometown, where her older sister, the local sheriff, offers her a spot on the local police force. When college girls show up dead in locker rooms, Sheila, facing past demons, must summon all her fighting skills in a deadly game of cat and mouse...
SILENT TRAIL (A Sheila Stone Suspense Thriller-Book 2) is Book #2 in a long-anticipated new series by #1 bestseller and USA Today bestselling author Blake Pierce, whose bestseller The Perfect Wife (a free download) has received over 20,000 five star reviews.
With her Olympic dreams crumbled, Sheila, 28, struggles to find her place back home. She is surrounded by reminders of what could have been, stuck inside the shadow of her older sister: the golden child, the respected sheriff. But when her sister persuades her to join the local police force, Sheila's life and career start anew.
As she hunts serial killers, Sheila notices clues that others miss and offers a perspective that no one else has. She realizes she has a talent outside of fighting, and that she has a chance to embrace a new life in Salt Lake-a life outside the ring.
This is a different kind of ring, though. Sheila quickly realizes that to survive, she will need more than just her strength-she'll need a brilliance to match that of even the most diabolical killer.
Can Sheila win this match? Or will she finally lose it all?
A page-turning and harrowing suspense thriller featuring a brilliant and tortured protagonist, the SHEILA STONE series is a riveting mystery, packed with suspense, twists and turns, revelations, and driven by a breakneck pace that will keep you flipping pages late into the night.
Future books in the series are also available.
