Martian Invasion (Tales of a Terrarian Warrior, Bk. 4)

After earning the Buckets of Bolts achievement, Miles returns home to take a break and hang out. But then Asher and Owen, warrior friends who joined him on the last adventure, come pleading with Miles for his help in battling Plantera. Things are dicey with Asher and Owen, as they need his help, but often treat him like a third wheel.

But who would have thought their biggest battle yet - and at home - would come not from Terrarian enemies, but those from outer space!
