Lexi embarks on his greatest adventure when his Uncle sends him a letter with strict instructions to board a certain taxi at a precise time and location. Accompanied by his pet hawk, Horus, Lexi arrives at the Rippleshank Estate in the dead of night. He meets his soon-to-be best friends, Fiz and Kimora, and they become inseparable, experiencing the fun, excitement and danger of the estate. The first thing they learn is that to remain at the lush estate, each of the one hundred guests must complete a series of tasks to test their skills and abilities. Their numbers dwindle as the kids who fail at the increasingly difficult tasks are sent home. When Lexi discovers the Rippleshank diary, it provokes their curiosity and they set off on a series of adventures that put them in mortal danger and require their success at death-defying feats, culminating in the final battle and the discovery of a lifetime - the Hawkeneye. Can you survive the Tasks of Rippleshank and command the power of the Hawkeneye?
