"The Open Portals - Part 2" by Katelyn Rushe on Amazon
Just as things are looking hopeful for Amber Brenin’s mission
back to Earth, an enemy fleet attacks the island where her team is resting and
forces them to split up. Those who can fight must stay behind to fend off the
invaders while those pivotal to the mission must find the island’s open portal
and go on without their allies. It’s one of the many compromises that Amber
will have to make as the war on Rökshena escalates.
Joined by Joe, Guido, and her father Robert, the girl soon
returns to Earth and begins her task of recapturing the Voxacustos one by one.
Tensions run high as her party sees the destruction that the creatures have
brought to her homeworld, and over time, her anger evolves into something much
harder for her to control. Relief comes when Earth’s militaries combine forces
to aid the mission, but if nothing can quell Amber’s raging emotions, then
everything on Earth and Rökshena will be lost forever—starting with Amber
herself.
