I was really looking forward to seeing what Sinestro would do, now that he’s sorta back in the Corps again, and this book doesn’t disappoint. The uneasy truce between him and the Guardians is quite interesting, and in a way he even works for them again by protecting his sector of space (which he does anyway). He also learns how volatile his own Corps is without him there to guide it, so it seems likely that he’ll eventually have to fight its new leaders to regain power, which probably means he’ll team up with Hal eventually.
I don’t know what else to say about this book. It’s fun, and it has everything I love about the Green Lantern comics. The only downside is that the scenes with Hal are mostly forgettable – possibly on purpose.
