Brilliant botanist Saffron Everleigh has set sail on her first research expedition, but it's disrupted by accusations of murder when one of her fellow scientists is murdered in this daring fifth installment.

Saffron Everleigh is newly engaged and full of optimism as she sets off on the adventure of a lifetime for any scientist: a research expedition. She sails to newly formed Turkey with her fiancé, Alexander Ashton, and a bevy of fellow researchers under the watchful and reformed eye of Dr. Henry. With only two other women on board, Saffron soon finds she is right back in the same infuriatingly misogynistic environment that marked the earliest days of her career. Only this time, Saffron is determined to show everyone, including Alexander, that she can handle the trials of an expedition.

And trials she has in spades. Before the expedition team has even arrived, Saffron has managed to find an enemy in historian Joseph Clark, who frequently torments the assistant that Saffron has taken under her wing, Martin Neill. But when Martin unexpectedly dies, Saffron is targeted as the main suspect.

Falling ruins, venomous snakes, and mysteriously blocked passages are the least of Saffron’s worries. With unexpected help from a familiar face, Alexander and Saffron have to work fast to prove not only that Saffron is innocent but that they both have nothing to do with a larger conspiracy at play among the expedition crew.
