Swamp Thing by Rick Veitch Book Three: Time Upon a Once

Thrust backwards in time, Swamp Thing must make sense of a universe drawing him towards its very inception. With the birth of the Sprout approaching, Abby desperately searches for answers and her missing husband while a monstrous entity from the past watches and waits. John Constantine will do whatever it takes to bring the Swamp Thing home before Hell, the Green, or worse comes to get them!

The final chapter to one of Swamp Thing's most legendary saga collects Swamp Thing #80-87, Swamp Thing Annual #5, and Swamp Thing 1989 #1-4--the lost Swamp Thing #88-91 issues, released at last in 2026 and collected here for the first time!
