THE used bookstore for book-loving kids (and grown-ups, too) Sam’s Books is a one-man operation, owned and staffed by Sharon Micek, a booklover whose passion for books led her to renting a stall at Oldsmar Flea Market on weekends over 20 years ago (possibly driven by the fact that her daughter was too old for kids’ books at that point and she needed an excuse to continue reading them).
