Umbra: Sentient Stars

By: Amber Toro

Narrated by: Megan Carver, Benjamin Farmer

Umbra is the first book in the Sentient Stars trilogy, an intergalactic, space opera, adventure story, with a slow burn enemies to lovers romance, told from 3 POV’s with fully sentient starships, a militaristic society, alien worlds, and a signal in the darkness that threatens to destroy humanity.

Earth That Was has faded into myth. After millenia spent wandering, humans are no longer nomads. Twelve tribes stand allied under the United Tribal Axis; but there is a signal in the darkness that threatens to destroy everything.

All Skyla wanted after leaving the Navy was to be left alone. Just her ship, the stars, and a new adventure. But when a strange virus disables her ship, she is thrown into the middle of a conflict she doesn’t understand, forcing her to take on responsibilities she swore she never would again.

Hinata always followed the rules, honor above all else. He always won, until he didn’t. Sentenced to exile for his failures, he is determined to prove himself, until a mysterious woman arrives on his station and chaos threatens to break already fragile alliances.

Freyja was always angry, an outcast, playing the part of admiral and black ops operative. But she is tired of being a pawn in the Empress’ games and when she’s stranded on the wrong side of enemy lines after a vengeful battle, she’s forced to ally with her adversaries to clear her name.

A Rogue. A Commander. And an Admiral. Brought together by circumstance, held together by duty. Can they find a way to work together to save humanity?

Absolutely Fantastic!

Wow! This was such a great listen. The narrators did such a fantastic job with this. And Amber delivered such an amazing story that had me hooked from the start. I absolutely can not wait to see what's coming next with that ending.

Such an enjoyable adventure!

I love this book, this is my second time reading and first time listening. This book had me at page one. Umbra stands out as a well developed, thoroughly enjoyable space opera with a cinematic feel that checks all the boxes of a good sci-fi. The moderate pace struck a nice cadence while allowing the depth required for a well thought out galactic world. The growth that happens for the characters was palpable. This book has heart and I'd recommend it to any reader looking for their next great adventure.

Perfect for fans of Throne of Glass and Skyward

Umbra is awesome. I LOVE the worldbuilding and the sentient starships! It’s a fun story and well performed too. It’s definitely perfect for fans of Throne of Glass and Skyward, and even fans of Firefly too!

Excellent space opera

Dual narrators did a great job. Second half of the book was edge of your seat awesome!

Great start to the series

I really liked this sci-fi, I think the story, plot and relationship was done beautifully. It had just enough adventure and suspense of what was coming next that it kept you wondering. And the way the relationships and friendships were done was perfect. I loved how the backstories fitted in and how the AI was done. I think the ships are my favorite characters lol. This does leave off on a cliffhanger but it's done so well that you get closure on most of it while just continuing the story enough past, to leave the cliffhanger on the next part of the story. I can't wait for the next book!

Scifi Perfection

I read this book when it came out and was so excited for the audiobook. Hearing the story made it so much more real and brought the characters to life immensely. The narrators both did amazing jobs and told the story perfectly. I like the characters but I LOVE the ships!! Someone give me a sentient starship to explore the galaxy with.
