To save the world, Mars must invade Earth.

Drafted (Homeworld Trilogy #1): The Earth is dying, overrun with pollution that the government refuses to stop. 16-year-old Tess is a proud Earther who wants to save the planet, but the government would rather ship everyone to Mars by force.

And no one hears back from the Red Planet.

When Tess's turn comes to board a one-way ship, she discovers a horrible truth: an alien race wants Earth for themselves. And Mars is a place where colonists struggle to survive. All Tess wants is to get back to Earth, but by running into Matthew, a fellow colonist with some secrets of his own, she gets wrapped up in a dangerous plan to do so: she must join an invasion of her former home.

Invaded (Homeworld Trilogy #2): The war between Earth and Mars has begun...

After learning that an alien race—the Grounders—now control Earth, Tess and her new friend Matt are in trouble. They're the first wave of an invasion from the Mars colonies, and they might be the only hope of taking Earth back from the Grounders. Worse, Tess's parents have been kidnapped by the aliens, and not all humans are bent on helping them take down the Grounders.

But Tess knows who she is: a strong Earther, with a mission to save the Earth.

But the biggest danger to Tess may not be the Grounders themselves, but a new revelation that will unravel everything she thought she knew. There is no telling what Tess will do next...or what she will become.

Infected: Tess and Matt have reached the final part of their journey. All that remains is taking down the Great Council and stopping the Grounders once and for all. But after a horrible revelation that's shattered everything, Tess isn't sure if it's even moral to continue on the mission - and she isn't sure who she even is anymore.

But when the full horror of the Grounders' plan for humanity is revealed to Tess and Matt, they will have no choice but to continue the war and risk their lives to bring down the Great Council. Also, Tess learns that her mother was hiding a secret about the Grounders, a secret that could decide the fate of Earth.
