Perfect for you if...
- You love first-contact stories that flip the script and make you sympathise with non-human intelligence.
- You're drawn to mysteries set in genuinely alien environments where the setting itself feels like a character.
- You appreciate hard sci-fi that explores what happens when we finally meet minds as complex as our own.
Maybe not for you if...
- You want fast-paced action from page one; this builds atmosphere and tension methodically.
- You prefer land-based adventures; nearly the entire novel takes place on water or beneath it.
- You're looking for human heroes to root for; the real intelligence here belongs to the cetaceans.
