I've been reading a lot of old material within the marvel universe since I am a new reader. But I am very interested in getting into the new guardians and the infinity wars event.
In the first issue of All New Guardians, they mention some events on earth that the guardians experienced, and also that something happened to groot with the gardener planting his spawns..
Is there any reading material that covers these events besides reading further issues of the All New Guardians?
