But when a reconnaissance ship returns to her idyllic domain, and its crew is mysteriously slaughtered, Ofelia realizes she is not the sole inhabitant of her paradise after all. And, when the inevitable time of first contact finally arrives, she will find her life changed yet again–in ways she could never have imagined...

I couldn't have written it; it required too much real physics."--Larry Niven "This is one for the real science-fiction fan."--Frank Herbert"Robert L.

Dyson"Forward has impeccable scientific credentials, and . . . big, original, speculative ideas."--The Washington Post
