I'm reading The Clone Redemption by Steven L. Kent. It is part of a Military Science Fiction Series and has been on my TBR shelf for several months. Here is the opening line:
"If this is supposed to be our funeral, I'm not impressed," Chief Petty Officer Robert Humble whispered to the clone standing next to him."
Here is what Goodreads says about the book:
Earth, 2516 A.D.: The Unified Authority has spread human colonies across the Milky Way, keeping strict order with a powerful military made up almost entirely of clones. But now the clones have formed their own empire, and they aim to keep it...no matter who they must defeat.
