L.L. Reaper is, actually, two people. I was amazed to hear it, they write as one, so I decided I had to read it and I had to interview them and find out HOW they manage to do it! Their book, Black Widow and the Sandman is already out on paperback.
From Amazon:Children in Cuba are suffering an agonizing death. The cause-a toxin released by a terrorist organization hell-bent on genocide. The scientific community is at a loss, and the Cuban government can no longer hide the truth from its citizens. Cuba's only chance lies in the capable hands of a reclusive scientist from the country that is believed to be behind this terrorist attack-the United States of America. Roman "The Sandman" Tate is the most sought-after mercenary in the world. When he is ordered to protect scientist Jeanette "Black Widow" Mason, he finds she is much more than scientific equations. The two join forces to create an antidote and stop those responsible for the mysterious illness before more children die and Cuba follows through on its promise to retaliate.
