Fablehaven: Grip of the Shadow Plague

This book picks up where "Fablehaven: Rise of the Evening Star" leaves off, during the same summer of the second year at Fablehaven. Sometime during the Summer, Kendra is requested by the Captain of 'The Knights Of Dawn' that she should be recruited, and for the first time, Kendra and Warren must visit another magical preserve, called Lost Mesa, that is located in the state of Arizona. They reside there, with Lieutenant Dougan Fisk, and dragon tamer Gavin Rose (whom Kendra has feelings for). Another hidden artifact must be recovered from Lost Mesa, before The Society unveils it first. However, Patton Burgess had already recovered the artifact and taken it to Fablehaven.

Meanwhile, Seth discovers that someone, or something, has released a plague throughout Fablehaven, before the others but as the disease spreads throughout the preserve, it is clear that they can no longer protect the preserve. Creatures of light are transformed into creatures of dark. As light creatures can enter most places throughout the preserve, the same rules apply to their darker forms. Seth is stuck at Fablehaven, where he, his grandparents, Tanu, and Coulter must try to solve the mystery of a new plague that is transforming the magical creatures. Seth discovers that he has gained new abilities with destroying Fablehaven's revenant. He is able to shadow-walk, hear the voices of prisoners from the dungeon that dwell underneath the main house, and speak the language of many creatures such as imps, goblins, trolls, demons, and giants. (Kendra can recharge magical artifacts, see in the dark, control fairies, glow very brightly, and talk to many magical creatures like Seth.)

After coming back Kendra learns that Warren, Grandpa, Grandma, Dale, Tanu, and Coulter are shadows. Also, when Seth sneaks into the manor, he finds a mysterious black woman that he remembers as a former ally Muriel and Bahumat. However, she also learns that Seth has brought Patton to the future for three days using the Chronometer. Patton tells Seth and Kendra that the woman-the cause of the plague-is a fallen hamadryad named Elphira. He says that she became mortal and went to Kurisock, another demon, to help her regain her immortality. Patton helps Seth and Kendra shut down the plague using a stone provided by the Fairy Queen and Lena dies when they shut down the plague.

After the plague is stopped Dougan came to escort Kendra home. He also said the Sphinx was their greatest enemy.
