Denis Markell. Denis has written everything from off-Broadway musicals to television comedies and even funny birthday cards for family members. His first novel for kids was Click Here to Start, where friends find themselves in a real-life video game. His latest, The Game Masters of Garden Place, is based on his son’s Dungeons & Dragons game (well, except the part where the characters come to life…). This is Denis’ first Lititz Kid-Lit Festival.
