The Overthrow series by Kenneth Oppel

Bloom, Hatch, and Thrive are the individual titles in the Overthrow series. This was a lot of fun to be able to read one right after the other, rather than spaced apart. The action dramatically changed from the first half of book one to the end of book three. In fact, the world changed so much that iwas almost hard to remember how different things were in book one.
This was some kooky science fiction adventure. As our house is always fighting a battle against invasive mugwort, I found the idea of alien invasive plants relatable. But thank goodness my mugwort is not a carnivorous weed nor trying to eat me.
In book one three teenagers who are oddly unaffected by the alien plant invasion try to figure things out and fight back. Book two ratchets up the doomsday vibe of Earth as reasons for the invasion become clear. Book three is, of course, and all out battle.
This was one of those sci fi stories where you think from time to time “even if they win the world is still ruined and a LOT of people died.” Because man, did those alien plants have the upper hand.
This was pretty exciting and all fast reads. I enjoyed this trilogy!
