Sinestro, Part One

Oh, Sinestro on the cover. What awaits inside? Ah! "Sinestro Part One". Neat.

And it's intriguing. Hal's not a Green Lantern anymore. Sinestro is. Hal's not adjusting well. And Sinestro says to him, at the end: "If you want your ring back, you'll do everything I say."

So, some time between five years ago (Justice League, Part One) and today, Hal Jordan has saved the Green Lantern Corps and also had his position stripped, apparently on account of his recklessness.
