Poderia ser " Os caprichos da criação " de Simon Hawke.
De uma revisão on-line:
The Agamemnon is a generation ship. Ten miles in diameter and even more in length, it carries hundred thousand humans and multiple AIs on a slowship trip to the stars.
It's a dozen generations into the trip by now, and things are working perfectly. Except in the last five years depression's on a major upswing, and there's been almost a dozen suicides.
And now Ulysses, Jenny, and Riley are getting sucked into a new kind of VR sim. And strange creatures are appearing on the decks of the ship. What the heck is going on?
Outra revisão descreve a simulação se descontrolando:
On the Agamemnon strange things are happening. A botanist studying damaged herb plants encounters tiny humanoids with wings. A young woman coming out of a broken relationship is seduced by an elf. A security skimmer has a mid-air collision with a dragon. Three teenagers experience a different virtual reality simulation than the rest of their class.
De esta página, um ponto importante do enredo:
As the baffled, frightened colonists search for answers, a young misfit named Ulysses stumbles upon a clue -- an alternative virtual reality within an interactive cybergame. A place where anything can happen, because the software is alive.
E a razão para esses eventos estranhos:
All of these elements tie in with an intelligent program set up by a crazy genius during the first generation. She had a plan in mind and it is up to some teenagers, the head of security, a biologist and a professor to determine just what the threat is and how to deal with it.
