This book has Swamp Thing in outer space for a fair part of it, as he encounters various other dc figures in his travels, such as those from the planet Rann, and the odd Green Lantern, and even the New Gods.He does eventually end up back on Earth, and is a little peeved with some of the bad guys.As The Shadow would say, if Swamp Thing is after you, 'The weeds of crime bear bitter fruit.'
