"David Harten Watson explores complex relationships and layered characters in this delightful second adventure. Watson has a humorous and charming flip on the idea of characters in a strange new world, only this time, the new world is our own. They encounter a new language, horseless carriages, and the strangest magic of all: technology. Watson has plenty of jokes poking fun at society and technology that are clever and charming. Their time on Earth also has a thriller element woven into it as the FBI [is]...determined to catch them.... Each part of the plot is coupled with humor, family, first love, and plenty of romantic complications. ...While dealing with heists and break outs, these teenagers are also dealing with matters of the heart rooted in Pran's feelings for Vitina and her insistence on those feelings being a side effect of her healing him. This leads him to explore his own feelings to figure out what's real, which is complicated when he figures out he has feelings for another boy. The romance is sweet and charming.... Fortress of Gold is a fun adventure with humor, action, romance, friendship, magic, and an unforgettable heist." (Liz Konkel, five stars, Readers' Favorite)

"Fortress of Gold has it all: romance, deceit, jealousy, a villain, pizza, ghosts, alien bodies, a cat, a wounded warrior, counterfeit money, pizza, the FBI, spine-tingling adventure, and, oh yes, pizza! The author has topped his previous effort in this series, producing great fun for the reader." (Thomas Wm. Hamilton, author of Time for Patriots, The Mountain of Long Eyes, and several astronomy books; retired astronomy professor who worked on the Apollo project)
