Till the Stars Fade — Karen Sandler

In the year 2123, humanity has pushed beyond Earth into the solar system and unlocked the secrets of life with genetic engineering. But despite the lifesaving cures and physical improvements wrought by the mastery over human DNA, some consider gene-tweaking an abomination.

Bold and reckless shuttle pilot Krys Krysynowski has thrown her lot in with SEIS, vocal opponents of genetic experimentation. But when SEIS sends Krys to the asteroid-based laboratory of Ian Llewellyn, her intense attraction for the lone-wolf geneticist shakes her to the core.

Krys's mission is to sabotage Ian's latest project, but his single-minded drive to conquer human illness turns her entire belief system upside down. Then she discovers the truth about Ian, and she faces a choice. Betray him and her growing love for him. Or take a risk that might keep her at his side -- but will most likely end her life.
