Killer Exposure

Toxic chemicals and instant chemistry in this tale of murder, medicine and combustible attraction! One minute Hannah Baker is a quiet science professor. The next, a possible murder suspect. Six victims, one per week, all poisoned with the same exotic chemical Hannah once worked with. Now she's wanted by Houston detective Owen Randall-but is it to enlist her help, or arrest her? Owen knows the prim Hannah is hiding something, but he isn't sure she's a killer.
Especially after some unfortunate incidents. Is she the next victim of the chemical killer? Torn between duty and his growing feelings, Owen only knows he has less than a week to save her.
