The Titanic is meant to be unsinkable, but as it begins its maiden voyage, there's plenty of danger waiting for four of its young passengers. Paddy is a stowaway, escaping a deadly past. Sophie's mother is delivered to the ship by police -â¿¿ after she and Sophie have been arrested. Juliana's father is an eccentric whose riches can barely hide his madness.

It's Christmas, but leave it to Sammy Keyes to find trouble even in the midst of the holiday parade. Trying to help a friend, she reluctantly volunteers on the Canine Calendar float, only to have the famous cover dog dog-napped on her watch! The animal's owner orders Sammy to find the dog before the $50,000 ransom being demanded comes due.

In her most dangerous mystery to date, Sammy runs into a strange girl trying to escape from a scary looking guy at the mall. When the girl asks Sammy to watch her shopping bag and then flees, Sammy is alarmed to discover that inside the bag is a baby!

In this fifth Sammy Keyes mystery, the normally unflappable heroine encounters a corpse, an arsonist, and an irate policeman - and her first real experiences with adolescent angst.

On a snowy night, Cara and her grandmother are pursued into St. Christopher's church by an unknown man. Clutching her grandmother's mysterious amulet, and following the old woman's instructions, Cara escapes their pursuer and falls into Luster, the world of the unicorns.

In the center of Luster towers an enormous tree that is the Heart of the World. Now the tree is wounded, pierced by a tunnel that connects it to Earth. Through that tunnel strides Beloved, the ancient enemy of the unicorns, followed by an army of Hunters eager to destroy every last unicorn.

In the third volume of the Unicorn Chronicles, Cara Diana Hunter journeys to the Valley of the Centaurs in quest of a mysterious lost story that could hold the key to the survival of the unicorns.

Bayern has triumphed in its war with Tira. But though the war is over, simmering anger remains among the Tirans and new hostilities could erupt at any moment. In a desperate attempt to maintain the peace, King Geric sends an ambassador to the Tiran capitol. Of course, an ambassador needs a military guard.

In The Lost Hero, three demigods named Jason, Piper, and Leo made their first visit to Camp Half-Blood, where they inherited a quest:

Seven half-bloods shall answer the call,
To storm or fire the world must fall.
An oath to keep with a final breath,
And foes bear arms to the Doors of Death.

Annabeth is terrified. Just when she's about to be reunited with Percy - after six months of being apart, thanks to Hera - it looks like Camp Jupiter is preparing for war. As Annabeth and her friends Jason, Piper, and Leo fly in on the Argo II, she can't blame the Roman demigods for thinking the ship is a Greek weapon.

Young Demigods,

Your Destiny Awaits!

Before Wicked was formed, before the Glade was built, before Thomas entered the Maze, sun flares hit the earth and mankind fell to disease. Mark and Trina were there when it happened, and they survived. But surviving the sun flares was easy compared to what came next.

"We want you to do it again."

These words, spoken to Brian Robeson, will change his life. Two years earlier, Brian was stranded alone in the wilderness for 54 days with nothing but a small hatchet. Yet he survived.
