I received an eARC from the author in exchange for an honest review. Thank you kindly to Joshua David Bellin for my review copy.

The Last Sensor picks up fifteen years after the devastating war that nearly destroyed the City of the Queens. It has been a time of stability and peace as Queen Rebecca and her people reconciled and learnt to co-exist with the Ecosystem. But a new threat has arisen. The Ecoystem is dying, and Queen Rebecca cannot stop it. It falls to Hadassah, a sensor-in-training and daughter of Miriam and Isaac, to set out and determine the cause and find a cure. This quest is deeply personal for Hadassah, as she also seeks out to find her friend and guardian Sarah, the former queen who led them to victory. Hadassah must venture into uncharted territory — a place of wonder, danger, and unimaginable power — in order to save her family and everything in the Ecosystem.

This series just keeps on giving. To say I was happy to find that House of Earth, House of Stone was not the final book, and that we were in fact being gifted another adventure into the Ecosystem…well, that would be an understatement. With the state of the world at the moment, delving into the familiar world of the Ecosystem for a last hurrah was exactly what I needed.

As the novel picks up fifteen years after the events of House of Earth, House of Stone, we have a fresh, new voice taking the lead. Hadassah is the daughter of Miriam, who is now Chief Sensor, and Isaac. A character who is unsure of her place in the world, someone who dreamt of exploring the Ecosystem with Sarah, and who is insecure in her Sense — or lack thereof. Her apparent lack of natural affinity for Sensing is a point of contention between herself and her mother, and Hadassah feels confined by the path Miriam has set her. She was someone who surprised me in a lot of ways (all good) and someone who I found myself connecting with.

If you’ve followed my reviews of this series (the links can be found just here — Ecosystem (#1), The Devouring Land (#2), House of Earth, House of Stone (#3)) you would know how much I loved Sarah as a protagonist. Hadassah had some big shoes to fill, but she did it with ease. She’s a very different character from Sarah, that’s for sure. But she has the same kindness and strength that I adored in Sarah. Hadassah has had a bit of a sheltered life and knows little outside the comforts of the City of Queens. Her venture into the unknown brought out her insecurity and her fear, but also of her quiet determination and strength. I rather enjoyed her progression and growth throughout the novel. I particularly enjoyed Hadassah’s budding friendship with Peter, her know-it-all nerdy travel companion!

I don’t want to spoil anything in regard to Sarah and her character arc, but her resolution is exactly as I would have expected. For readers returning to the series, there is also plenty of familiar faces who make an appearance, and it was lovely to see where they ended up fifteen years later.

I also loved that we got to explore uncharted territory and discover something unknown, ancient, and well…deadly. We delve even further into the origins of the Ecosystem to a time that pre-dated it’s existence — to a power now driven by rage and revenge. Immersive storytelling and fantastic world-building, as expected!

To conclude, if you’re a fan of post-apocalyptic, environmental, and survivalist literature, the ECOSYSTEM is a series you need on your radar.
