Packed with Niven and Barnes’s trademark excitement and science-based extrapolation, this thrilling novel introduces readers to Ice Vegas, an extraordinary city of the future powered by nuclear fusion.

Carver Reeves is head of security for BALDR, the massive nuclear facility that powers half of Europe, and by extension Ice Vegas, the glittering architectural fantasia of a domed city that has grown up beside it.

It’s Carver’s last week on the job, and he can’t wait to clock out for the last time. He’s spending Christmas with his estranged daughter and meeting his grandson for the first time.

Prime time for a disaster.

Saboteurs have infiltrated BALDR, determined to cripple the power plant, destroy the city, and kill hundreds of thousands of people.

Carver’s only hope: Spider.

A deadly chameleon who sells her services to the highest bidder, Spider has killed more times than she can remember. Her true past is buried under layers of false identities and implanted memories.

She’s been hiding in Ice Vegas for a while now, after an unsanctioned assassination. She’s made friends. She’s never had friends before.

She’d like to keep them.
