A Shot of Red — Tracy March

After fleeing DC following a one-night stand that had her reeling, biotech company heiress Mia Moncure has thrived working with a humanitarian aid team administering vaccines in Haiti. When the United States is threatened with a flu epidemic, Mia's grandmother demands her return to unveil a new flu vaccine for Moncure Therapeutics. She arrives to find that her ex-boyfriend, the company's PR Director, has died in a suspicious accident in Switzerland that Mia soon suspects was murder.

Determined to reveal a killer, Mia heads to Switzerland, where she's threatened as she discovers a plan to infiltrate the vaccine for nefarious purposes. Desperate for backup, she turns to sexy Gio Lorenzo, Communications Director for her mother, a high-ranking senator--and Mia's one-night stand. While negotiating their rocky relationship, they race to uncover a deadly scheme that could ruin her family's reputation. But millions of people are being vaccinated, and there's more than her family's legacy at stake. Mia and Gio struggle to discover the truth about the scheme and their feelings for each other, but it just might be too late.
