Alien Agent Zack Gaither has spent his whole life on planet Earth. His assignment: to protect humans from the knowledge of life on other planets. Finally, the time is right, and Zack has the chance to help Earth join the Galactic Union. The only problem? A small army of alien thugs is set on keeping Earth out of the picture. And they're planning to take Zack out in the process. Fortunately, Zack's got a few old friends on his side. Together, they're headed on an adventure that will take Zack off of Earth and across the galaxy. What will the future hold for this Alien Agent?

Tsynq Yr, a Sylon scout and pilot, is flying a stolen spaceship behind the enemy lines of the Zarnk Empire. In the course of evading a Zarnk battleship, the Sylon crash-lands his vessel on Earth. Grave injuries force him to abandon his body and assume the form of the only available host — a skunk! The alien's luck improves when he chances to meet Karen, a girl who dreams of space adventure. Thanks to his powers of telepathy, he can communicate with his new ally, who gives him the all-too-fitting nickname Stinker. Although he finds Earth technology primitive, Stinker is helpless to return to Sylon with crucial information for the battle against the Zarnk. Karen enlists her computer-savvy classmate, Jonathan, in carrying out an ambitious plan to "borrow" a space shuttle. In the meantime, the three must avoid drawing the attention of their families, NASA, and the Zarnk as well as the local skunk population. This thrilling escapade will enchant young science-fiction fans.

In this first book of the Alien Agent series, we meet Zack, a normal kid with a crazy cousin, Ethan, who thinks he's an alien. But is Ethan really crazy? And why do the same bald, odd-looking fat guys keep reappearing everywhere the boys go?

Suddenly, a visit to an ancient stone circle whisks her back into the past. She has been summoned, along with Arni, a boy from Viking times, and Tyaak, a half-alien boy from the 26th century, to search the past, present, and future for three broken sections of a magical wooden staff. As the trio experience each other's worlds, they find deeper mysteries to probe and problems to solve, which could affect the entire time line of the planet.

Zack knows he's not a normal kid. He's really an alien agent-in-training, brought to Earth to help guide the planet into the Galactic Union. Aliens follow him to a ritzy summer camp, where he's hooked up with Vraj, a huge, dinosaur-like creature on her first-ever assignment. Their mission: To get back a bunch of alien Duthwi eggs that, if hatched, can harm Earth. Their problem: Lots of eggs, too little time, and those bad guys are still after them. So what's a young alien to do?

The little stinker is back!

He's been charged with an urgent mission to find something uniquely "earthly" for a galactic ruler's collection. Even though Karen and Jonathan are still in trouble from last time, they can't refuse Stinker. The trio plunges headlong into a madcap quest through Washington, D.C., with the police and NASA officials hot on their trail. Their funny, fast-paced adventures will charm science fiction and fantasy lovers of all ages.
