The Mask of Destiny is the over-the-top smart and action-packed conclusion to The Archer Legacy trilogy. Readers who enjoyed the first two books will be thrilled to finally resolve the mysteries, and have all of their lingering questions answered. This exciting story reads like a young teen version of the movies National Treasure or Indiana Jones--the European locales are exotic and the clues are cryptic, all leading to the big final reveal of the true nature of the Archer family legacy that Gerald was born to protect. The children are in very real peril along the way, as they are shot at (ineptly), kidnapped by a poison dart specialist, trapped by incoming tides on a sheer cliff, and lost inside a network of ancient Grecian tunnels. One evil-doing adult does die, although it is not under the circumstances that readers expect. Friendships are tested by the interference of a meddling adult, but ultimately the kids' trust in their relationships wins out. The publisher's recommended age is eight and up, but because of the complexity of the plot, it is probably best suited for mature tween readers or young teens.
