Help me.

English teacher Corazon da Silva attends the funeral of Isabella Morales, but soon afterwards, two desperate words whispered over the phone shake her to the core. Is her best friend really dead?

With little interest from the Colombian police, Cora goes undercover to hunt for Izzy in America. The journey promises to be dangerous, but she's not worried because her big brother, Rafael, is watching her every move.

The only problem? Rafael's an assassin, and he's just shot somebody he shouldn't have. Now they're in a race against time to find Izzy before his enemies catch up with him, and Cora isn't the only person with a hidden agenda.

Quicksilver is a standalone romantic thriller novel in the Blackwood Security Series. No cliffhanger!
