In this third installment of Pearson's Sun Valley series, KILLER SUMMER takes us back to the high-stakes world of the wealthy and politically connected – just in time for the area's 17th Annual Wine Auction. The world's most elite wine connoisseurs have descended on Sun Valley to taste and bid on the world's best wines, including three bottles which are said to have been a gift from Thomas Jefferson to John Adams.

With sky-high prices all but guaranteed for these priceless items, it's no wonder a group of thieves is out to steal them. Sheriff Walt Fleming is responsible for all aspects of the auction, from security of the dignitaries to the physical safety of the auction site to the transportation and security of the rare wines themselves. When a bomb explodes just as the auction revs up, Walt is thrown headlong into the fray, investigating not just an explosion, but an even bigger heist planned by a criminal mastermind who will stop at nothing to gain his prize.
