Shiver / Karen Robards / 503 pages / St. Louis Challenge

I found this book's premise a bit difficult to believe.  Samantha Jones is a 23-year-old gun-toting tow truck driver who collects repossessed cars in East St. Louis.  She is a frugal single mother, taking EMT classes so that she can provide for her four-year-old son, Tyler.  When she hooks up a BMW to tow, she discovers a man in the trunk.  Sam ends up in the trunk as well, as drug runners are determined to deliver Marco to their boss.  Marco is really Special Agent Daniel Panterro, posing as Marco while the real Marco is in protective custody giving evidence against the drug cartel.  Danny is rough and bossy; Sam is clever, self-sufficient, and quick-witted; Tyler is one precocious four-year-old.  This happily-ever-after page-turner is a quick, rather harrowing read.
