Trigger warnings: disappearance of a friend, violence, shady government stuff??

I didn't know this existed until I picked up New World and it started with an author's note saying that you needed to read this first to fill in the gaps and I WAS NOT SUPER PLEASED ABOUT THAT TBH. Personally, I think that 0.5 books should offer extra content but shouldn't be required reading in order to understand what's happening in the next book in the series.

But whatever. It was only 99c so it wasn't the end of

DIFFERENT WORLDS is a short, fast-paced novella that manages to both deepen the series its a part of (The Iamos Trilogy) and stand on its own. I came in expecting to enjoy myself thoroughly--Henry was always my favourite in FOURTH WORLD, and this novella is about him (and Tamara). And I was right. The plot is great, the character arcs are deep despite the limited space, Lyssa even made me care about a romance I wanted *nothing* to do with when she first hinted at it (this n-o-p-e happens a lot, ...more

LOVED this novella! I'm a huge fan of Lyssa's book, FOURTH WORLD, which I read last summer, and this companion novella really hit the spot for me. Let me start by saying that this novella should absolutely only be read after reading FOURTH WORLD, since it relies heavily on the events on the novel (plus, everyone should read FOURTH WORLD anyway because it's awesome).

In FOURTH WORLD, the main character, Isaak, is whisked away from his life in a Martian colony, and we, the readers, follow him on a

I picked it up and didn't put it back down until I finished the entire book. It's fantastic and brought me right back into the setting of Fourth World, which I'd read nearly three years ago now. I just received New World in the mail today and that spurred me to finally pick this up. I love Henry and Tamara, and I love their development in this novella. It really made me understand them more than I did in Fourth World. I'm looking forward to New World!

I really enjoyed seeing what happened on Mars while Isaak was away :)
I read Fourth World (which you should totally read and also read first, because otherwise you'll probably be confused) a while ago, but I held off reading Different Worlds until now because the second book isn't released yet and I didn't want to have one very long wait during the series. Now I'm kind of regretting not reading it earlier, because it's awesome, and also reading it already, because I desperately want to know what happens next.

I love both Tamara and Henry, the two POV-characters, an
