Vortex on Vertu Prime

The last thing Tania needs is someone else telling her what to do. Her mother does enough of that already! But during a school trip to the museum, she somehow finds herself gaining a bossy, alien teddy bear called Edward, who decides to adopt her.
When Tania, Edward, and her friends Mark and Windracer join Tania's mom on Vertu Station, they are put up in a 5-star hotel on part of the planet's sole remaining arcology; a massive, pyramid-shaped, self-contained city. But after Archaeologists accidentally activate an alien temporal warp generator, Tania, Mark, Windracer, and Edward are thrown backward through time.
With Edward's power reserves dangerously low, it is up to the three friends to reach the generator and turn it off-before it destroys the planet.
An exciting sequel to Crisis at Calista Station, Vortex on Vertu Prime invites readers to join Tania, Mark, and Windracer in a new adventure with new friends.
