SPOILERS AHEAD: Please read Books 1 and 2 in the ‘Finniverse’ series before reading this review.

Middle School

After his adventures through time, Finn returns home to a world he doesn’t recognize. Changing the past has created an all-new present, one in which he and his friends never vanquished the Plague. Now the giant bugs rule Earth from their spaceship! What’s an intergalactic traveler to do? The answer is obvious. Finn, Lincoln, and Julep must defeat the Plague. Again.
But how? Julep and Lincoln don’t remember Finn or their friendships. In fact, they’ve changed just as much as the world itself has, and they want nothing to do with his dangerous plan to save humankind. Finn’s plan? Find his father, Asher Foley, who is trapped in a microscopic world known as the Subatomic. Using a space-age slip-and-slide, Finn and his confused former friends shrink themselves to enter this strange new world where nothing is as it seems, hoping to find his father, the one man who can put history, and the present, back together.
It won’t be easy. The Subatomic is ruled by an evil menace with an army of hulking robots under his command. Even worse, Finn’s bitterest enemy, the Plague soldier Sin Kraven, is in pursuit. Can Finn find his father, save his friendships, and return to Earth in time to stop the Plague?

I should have skimmed through Books 1 and 2 before reading this book. I would have been able to follow along better. This is why I usually wait for all the books in a series to be published before starting a series. So I don’t have to wait between stories and forget details.

This story starts with the classic ‘changed the past and has come back to a present you no longer recognize’ trope. While Julep’s character and personality pretty much stay the same, Lincoln changed completely.

I enjoyed the beginning of the book, but once Finn and his friends shrink down to the Subatomic world, it was like a whole different story started. The characters stepped out of one war and ended up in another. I honestly didn’t like this story as much as the first two.

The ending is okay but a bit misleading. The summary says that this is the third and final book in the series, but the story leaves off with “The end . . . for now.” What does that mean? Will the author write a separate series about Finn and his friends?
