Immortal in Death (In Death #3) by J.D. Robb

It is 2058, New York City. Lieutenant Eve Dallas uncovers a world where technology can create beauty and youth, but passion and greed can destroy them.
She was one of the most sought-after women in the world. A top model who would stop at nothing to get what she wanted -even another woman's man. And now she's dead, the victim of a brutal murder.
Police lieutenant Eve Dallas puts her life on the line to take the case when suspicion falls on her best friend, the other woman in the fatal love triangle. Beneath the facade of glamor, Eve finds that the world of high fashion thrives on an all-consuming obsession with youth and fame-one that leads her from the lights of the runway to the dark underworld of New York City, where drugs can fulfill any desire, for a price.
Basic plot – there is a new drug in the making. ‘Immortality’. A drug people are willing to kill for. And between meeting the florist and being measured for her wedding dress Eve has to solve the case before her best friend is locked up for a crime she didn’t commit.
Dun, dun, duuuuuuuuun.
When Eve investigates the death of one of her informants she finds a strange unrecognizable powder and she quickly finds out that her informant was in a lot deeper than he could handle. But when her best friend Mavis is framed for murder and even all the evidence points to her Eve takes it personally.
Once again we get to see how far Eve will go to get the job done and what extremes she will go to to gain the truth. Eve is put into the same situation that her superior officer was put into in the last book – she has a personal interest in the case. But, unlike her superior, we see how strong she is as she still continues with her job, doing everything to the best of her ability.
In this book some of the minor characters also become a bit more main. And I am having fun learning about the people that pad out Eve’s world and support her.
