Welcome back for another installment of Preview Monday! This week, we’re giving you exclusive first looks at GREEN LANTERN #23.4: SINESTRO and TOM STRONG AND THE PLANET OF PERIL #3!

The Book of Parallax holds the entire history of Sinestro and his Corps. When the Green Lanterns – led by none other than Hal Jordan – came to Sinestro’s home planet of Korugar, they plunged it into chaos. They cursed Sinestro’s name and, ultimately, brought about the destruction of the entire planet. But what became of Sinestro? One never-before-seen moment from those dark days holds the key to his future! Written by Matt Kindt and illustrated by Dale Eaglesham, GREEN LANTERN #23.4: SINESTRO hits shelves this week.

Meanwhile, Tom Strange and his elixir of life must be found! But chasing him down on Terra Obscura proves more difficult than Tom Strong and Val Var Garm realized. They've arrived at the Grand Canyon, where millions of desperate refugees have gathered in New Egypt to escape the Red Death. But will they find their cure amid the crowd? Written by Peter Hogan with art by Chris Sprouse and Karl Story, TOM STRONG AND THE PLANET OF PERIL #3 lands in stores this Wednesday.
