Book cover for CHAOS VECTOR: title in white on red either side of a black u-shaped ship

Sanda and Tomas are fleeing for their lives after letting the most dangerous smartship in the universe run free. Now, unsure of who to trust, Sanda knows only one thing for certain — to be able to save herself from becoming a pawn of greater powers, she needs to discover the secret of the coordinates hidden in her skull.

But getting to those coordinates is a problem she can’t solve alone. They exist beyond a dead gate — a Casimir gate that opened up into a dead-end system without resources worth colonizing, and was sealed off. To get through the dead gate, she needs the help of the enemy Nazca. But some Nazca are only interested in the chip in her head — and they’ll crack her open to get to it.

The vibe of this book is a little different to the first. Rather than primarily feeling like a story about survival, truth, and encroaching war, CHAOS VECTOR takes the seeds of potential conspiracies in the first book and spins them out into a full about about multiple, overlapping conspiracies ranging across the galaxy and touching so many aspects of life. It makes it hard to know who to trust, and isolates the heroes. The scope of the story means the reader knows a little bit more than the characters (as the reader sees what everyone is seeing), but the information is controlled such that there’s not much more known – there are still so many secrets cloaked.

It certainly wasn’t the vibe I was expecting, but I really enjoyed it. The pacing is good, and the combination of action, secrets, and betrayals is compulsive. This is such a great sci-fi series!

There are more POVs in this book. As well as Sanda, Biran, and Jules, Tomas also gets a say and a small side character from the first book (Arden) is an occasional narrator. Plus there are a few interludes from the woman who took humanity to the stars. It felt like there were more when I was reading, but I can’t actually name any more! The characters are linked this time – some pretty lose threads at time, but they are linked. And that made it much easier to read them as I wasn’t struggling with completely-unrelated-to-the-others Jules any more.

Characters did, however, drop out for a very long time once more. Biran in particularly felt very underused and forgotten for stretches, as if he was being relegated to a back-seat character in favour of those directly linked to his sister’s adventures (the majority of the chapters were hers by a long stretch.)

The ending sets the stage for an explosive finale, and I’m so glad I have only got to wait a little over a month until it’s released. It really is great to start a series so close to its conclusion!
