Endgame (Mindspace Book 4)

Kira's nemeses are back, and they're after her home.
Captain Kira Elsar is adjusting to her new Robus abilities, but a series of strange attacks on the Tararian Guard's computer network throw her life into chaos.
A planet-sized ship appears out of nowhere, and it's heading straight for Kira's home system. With the lives of everyone in the Elvar Trinary-and Taran Empire-at stake, Kira embarks on a daring mission to stop the massive ship before it can attack.
Conventional weapons aren't enough to take down the alien vessel. Kira alone has the necessary abilities to defeat the Trols. This time it may be a one-way mission.
Endgame is the fourth installment in the Mindspace series, a space opera set in the Cadicle universe-perfect for fans of sci-fi with superhuman abilities, political intrigue, military action, and devious aliens.
