The Last Will and Testament of Hal Jordan

After Hal Jordan's death, his old friend Tom Kalmaku is down on his luck when Hal's will names him guardian of a boy who seems to be Hal's son, and who wears a power ring. The Justice League wants the ring, and a Dark Lantern built from Kilowog's spirit is hunting anything left of Hal's legacy.

It's a graphic novel about grief and what we owe the people we've lost, told from the point of view of someone who never had a ring.
