Lost in Space: Return to Yesterday by Kevin Emerson

5.0

Both of these LiS books by Kevin Emerson have a time-travel aspect to them and read almost like outtakes from the episodes, as if the producers of the Netflix show didn't want to go down the time-travel rabbit hole but Emerson was more than willing to oblige.

In the first one, Will, Robot and his sister Penny stumble upon some strange canisters in a cave and a space travel portal that can take them when and where ever they can picture -- even, before they left Earth.

They think they may've found a way to get out of their current predicament. Robot warns them, "Danger," but no one's listening. Unfortunately, Penny reaches through the portal and heads… back to middle / high school, to a time when she can get stuff -- like candy from the corner convenience store -- that she hasn't had in forever.

Awesome going home, right?

But then her actions, stealing an armful of candy and bringing it back to school and getting caught on surveillance cameras, sets events in motion that wipe her presence from the Robinsons' mission, splitting the family up forever and sending the successes the Robinsons have experienced so far into oblivion.

It's up to Will to figure out the time travel solution to the mess Penny's made of things. Add to that a few aliens upset that the Earth kids are using their technology in a way it wasn't designed, much less intended, and the Robinsons need all the help they can get from Robot to get out of this mess.

I think this takes place during Episode 4, season 1, when the Robinsons and Robot tag the cave as a "family."

We loved the Netflix series and enjoyed these books as continuations of our favorite space opera family's adventures!
