The Monoliths of Redshift 7

Admiral Victoria Heartness is thrown into the 25th century where sun-sized creatures known as The Monoliths are draining stars at an alarming rate. Assembling a team of humans and aliens, she is determined to save the galaxy at all costs.
But she hardly expected some of the most powerful races in the galaxy to accept their fate. With even the Interdimensional Coalition reluctant to help, it's a race against time to find a way to fight this unknown and seemingly unstoppable force. A fight that no one believes they will win.
