Dino Sword // Dragon Sword — Mark London Williams

San Francisco, December 1941.
Holiday jingles and air raid sirens mingle -- the U.S. has just entered World War II, and for 12-year-old Eli Sands the moment is particularly bittersweet. He has finally tracked down his mom who disappeared in a timesphere accident nearly 80 years in the future, but she now has secrets that bind her to this past. Eli's best hope is to enlist fellow time-wanderers, Thea and Clyne, to join him on a quest to Arthurian England. With a kick start from the legendary king and a bit of magic from Camelot's famous wizard, together they confront a horrific emissary from the 20th century. But will they be in time to save the world from tyrannical rule?

So continues the saga of three accidental adventurers in Book #2 of the Danger Boy series.
