I enjoyed the suspense and tension in this slow creeping mystery in this scifi horror novel. Ophelia, a psychiatrist from a rich family with quite a bit of buried trauma in her past, tries to save her name by joining a remote planetary reclamation crew as a therapist. The crew is tight-lipped and grieving a past crew member's death, and resent her presence (and her family). They all land on a planet to explore an abandoned station, and things quickly start to fall apart. It doesn't help that Ophelia is involved in trying to prevent ERS, a sort of "space madness" syndrome that causes people to get violent and paranoid.

What I enjoyed the most about this book was its slowly building tension. Traumas and secrets from the past intersect delightfully with mysteries in the present. There's a lot of delicious ambiguity in all of the creepiness. Are events just pranks or hallucinations or truly real? Are strange physical symptoms a sign of impending ERS? How much can Ophelia herself even be trusted?

This was just a solidly good horror book for me. Nothing world shattering, but all the threads are woven together satisfyingly.
