DC Universe: Last Sons, Alan Grant, 2006, ISBN 0446616567
Lobo is the meanest and most ornery bounty hunter in the galaxy. He is the sort of being who has no problem killing anyone who gets in his way. His next quarry, supposedly with a million-credit bounty on his head, is Jonn Jonnzz, Martian Manhunter of the Justice League.
Despite Lobos lack of morality, he does have a code of honor, being scrupulously honest. He also has a crush on Darlene, a waitress at a burger joint on an asteroid.
Meantime, somewhere in the interstellar middle of nowhere, an artificial intelligence called The Alpha hatches a plan to wipe out all life in the universe. When Lobo delivers Jonnzz, with Superman not far behind, all three are thrown in prison. But, this is not your average prison. The walls in Supermans cell are impregnated with kryptonite; Lobo and Jonnzz are similarly trapped. The only thing that all three have in common is that they are the last of their race (in Lobos case, it was intentional).
The Alpha plans to dissect them and use that emotional energy to create an invincible fighting force. Their release, and stopping The Alpha before it wipes out any more civilizations, depends on a crime boss named Xemtex. Lobo cut Xemtexs brain out of his head, and it now controls Lobos space bike.
Coming from a comic book "mentality" (for lack of a better word), its a very fast and entertaining read with plenty of action. Its recommended, especially for those who dont consider themselves comic book readers.
