I have reached a point where I am getting a truly absurd number of books every month through book box services of one stripe or another, and every time I think I’m going to get my shit together and cull one or two of them, I discover a book like The Radiant Dark, which was not on my radar in any way before it showed up and caught my interest via, in this case, my Aardvark box. Alexandra Oliva has written a couple of other books before this, but she’s new to me, and anything that can consistently feed me new authors that I like is going to continue to get my attention and my money.

The Radiant Dark is part alternate history, part science fiction, and part family saga; it starts in 1980, and at first I thought I had managed to pick up what feels like the third or fourth book in the last month or so featuring a struggling young mother with a baby and a useless husband. And, well, it is that, for a little while, but it doesn’t stay that way for long. Very early in, President Carter announces that a signal emanating from a specific region of outer space has been conclusively proven to have intelligent alien origins, from an unknown exoplanet approximately eleven light-years away. And because of the distances involved, any message that gets sent back is going to take eleven years for the aliens to receive, and 22 years minimum for Earth to receive any sort of response. The book isn’t solely concerned with the communications, of course, but there have to be time skips to keep it from being a thousand pages long. Oliva also has a defter hand with her characters than you might think at the beginning of the book, and the relationship between Carol, her son Michael, and her daughter Rosanna (called Ro for most of the book) is the emotional center of the book. Carol’s husband quickly becomes her ex-husband, but he’s a complex character in his own right, and while it seems clear who the hero and who the goat is early on, it gets muddled up nicely in the fashion of most dysfunctional families pretty quickly. Ro in particular has a very strained relationship with her mother, and she will eventually become a mother on her own. I genuinely feel like even if they hadn’t had the first contact/science fiction side of this book, it would be well worth reading just because of the way it explores the family dynamics.

Ro turns out to be a world-class astronomer, and is one of the first people to decipher the second message the aliens send us, 22 years after the original beacon. She is snatched out of her Ph.D program by a world-renowned scientist who wants to use the knowledge the aliens have sent us to start looking for other potentially habitable planets and, possibly, other intelligent life– although the aliens make it clear that all they have been able to find so far is us. She presents it as a generational effort, something that she doesn’t plan to survive to see the fruits of. By the time the book ends in the 2030s, humanity has colonized the Moon and sent people to Mars, so obviously there’s some divergence from our own history, as you well might expect.

I was not expecting to enjoy this nearly as much as I did, and this is the rare book that I will recommend because I find the characters so compelling. I like good character work, of course, but it’s rarely at the forefront of my reasons for liking a book, especially one so suited to my interests as a first-contact science fiction novel. But I think it’s best to read this as a family saga with a side dish of sci-fi rather than the other way around; if you go into this solely as a sci-fi person, I think you’ll come out disappointed. It’s not much of a spoiler to say that the aliens do show up eventually, but don’t read the book waiting for that reveal. That’s not the book Oliva wanted to write. Go in with your expectations calibrated appropriately, though, and you’ll end up with a read that I think stands a pretty good chance of showing up on my end of the year list. Check it out.
