A flu epidemic ushers in a plague of dark magic in this spooktastic mystery featuring teenage sleuth Johnny Dixon from The Wrath of the Grinning Ghost. Though forty miles away, Duston Heights is not safe from the flu that's raging through Boston. When Johnny Dixon's grandmother falls ill, he's sent to live with his neighbor to avoid infection. So many locals are getting sick that school is canceled for a week, and the reclusive Dr. Abram Ashburn comes out of retirement to make house calls. After seeing a scary vision of his bedridden grandmother outside of a window, Johnny starts to feel on edge. Then he and his best friend find what looks to be a weird map of a cemetery in Dr. Ashburn's house. One specific grave is marked with an "X," the burial place of a woman who practiced witchcraft in the seventeenth century. The townspeople recover from the flu, but they can't escape the terrifying illusions and shadow people that now haunt them, unless Johnny and his friends find the key to unlock the secrets of the graveyard before a dreadful prophecy comes to pass . . . Praise for The Wrath of the Grinning Ghost "Fans of the series will enjoy this new supernatural adventure, which reads so much like Bellairs's books that they won't believe he didn't write it." --School Library Journal "Strickland's story is eerie, suspenseful, and true to the personalities and writing style of Bellairs, who began the Johnny Dixon series . . . This is good reading for adventure enthusiasts as well as for series fans." --Booklist

From Bad to worse...
Landslides, a deadly climate, and the increasingly unpredictable weather of Mars make survival nearly impossible, but the most immediate problem facing the Marsport colonists is the dwindling water supply. The group decides to onstruct an automated station in a rift valley where ice accumulated from the atmosphere will be melted and moved through warming pipelines to Marsport.
The kids of the Asimov Project participate in the work, but then a fierce storm hits and a team that includes Jenny is isolated and lost. Despite orders not to leave Marsport, Sean puts together a group of kids to go out and find the team. As the race to save the missing colonists becomes increasingly dangerous -- and pits Sean against Amanda and the administration of the colony -- Sean quickly learns that schisms within the social order are almost as deadly as Mars itself.

There's no turning back. The year is 2085, and a new teen has arrived at Mars Experimental Station One, a colony built to test humans' ability to live self-sufficiently in an alien and hostile environment. Already in existence for ten years, "Marsport" is a functioning city of two thousand people -- with only twenty teenagers. These teens, part of the controversial Asimov Project, were hand selected from the billions on Earth and are always under the watchful eyes of the adults. The newcomer, Sean, is a fifteen-year-old orphan who acts tough but secretly thinks he can't measure up to the others. His companions are Jenny, also fifteen, an ethereal blond whose frail looks belie her fierce intelligence, and Alex, a fourteen-year-old pilot in training who doesn't always know his boundaries. They each have reasons to doubt themselves...and distrust each other. But one thing is certain: Mars offers them something Earth never could. When the existence of Marsport is suddenly threatened, the group must overcome their fears and join forces, for their survival depends on nothing less.

Five months into their undercover search for the pirate Jack Steele, Captain Hunter and the Aurora head for the island of Tortuga to put in for repairs after a battle with a deadly Spanish ship. Davy Shea, now fifteen years old and accepted by the Aurora's crew, continues to help his uncle Patch in the ship's surgery, but Captain Hunter has a special mission for him.

The Captain has learned that captured British officers are being held on the island for ransom from the Crown, and he is determined to rescue those officers, even risking the Aurora's cover. As a servant boy, Davy can easily pass among the various pirate groups thriving on Tortuga.

But as Davy begins to uncover the many secrets and deceptions that shroud this beautiful island, he soon realizes that more is at stake than the lives of a few captured officers. A plan is in the works that will force the pirate hunters on the Aurora to make new alliances...and bring them face to face with former enemies.
