Eternity row is the fifth StarDoc novel. After Cherijo finally managed to escape from Earth and get away from her narcissistic creator she finds herself back on the Sunlace with her adoptive people at the end of the last book. The vaguely hinted at secret she was hiding throughout the book turns out to be the child she miscarried surviving in an artificial womb and they are greeting by her when they arrive since it's been about a year. She didn't tell anyone, including her husband about the baby because she wasn't sure it would survive so it's a happy surprise to all of them.
This book opens on her trying to balance being a mother to an exceptional child and her duties as a doctor. And to make things more difficult seems to be taking after her mother in a lot of ways and there are some mysterious things that keep happening with the little girl that make it clear she has powers even beyond her mother's . But the main thread of the book involves the ongoing attempts to catch her, by the League, and the growing hostilities between the League and the Hsktskt faction. Both want Cherijo for their own use so she's caught in the middle.
This story seems to have a theme of family commitments. She promised to visit the home world of her foster mother for answer, and has also promised to bring her half-human friend Hawk to the world his father came from so they can meet, and then they are off to Dhreen's home world. Even though her friendship with him was badly damaged by his betrayal and she no longer trusts him she has still agreed to go to his home planet and help with a mysterious illness they have which keeps them from having children. Once there though she finds out that things were even worse than he'd hinted. In fact they are unbelievably bad, on top of that she runs into some old enemies, the Bartermen as her past comes back to bite her. The Bartermen have had a grudge against her ever since the first book and they immediately take the opportunity to make her a slave, but they still need her medical skills to deal with the plague of eternity that's infested Dhreen's planet.
There's a lot of coincidences in this book and at times it strains the belief, even for sci-fi. Hawk's father's home world coincidentally becomes very important to solving the problem on Dhreen's home world--and visa versa. Her sentient cat friend alunthri just happens to resemble a local god-creature and is able to save them from trouble with the locals. And then coincidentally the planet her foster mother insisted she go to (from beyond the grave) for all the answers to her origin, just happens to be nearby both planets so it's a nice straight shot from one to the next. I love it when my errands line up like that too, but this is a huge universe so it seems fairly unlikely that all these things end up matching up.
I really enjoyed this book though I admit it was painful to see Dhreen as a bad guy, and to watch their once great friendship be so cold. And it was frustrating that she wouldn't even let him explain his betrayal, but seeing the secret he'd been hiding from everyone did help quite a bit to mend things and they are in better shape when they leave there and go get her foster mother Maggie's secret. Except of course, it's never that easy.
I would have given this book a three just because it was straining the imagination, but the new aliens we encounter were just so much fun and I got really invested in the mystery of Dhreen's home world. It was heart wrenching and definitely worth 4 stars.
