Description of Vanishing Act by Jennifer AlLee
Juliet Button doesn't even believe in ghosts, but she believes in supporting her makeshift family of misfits. Having spent years as assistant to her uncle, an illusionist, she now has all of the skills and know-how she needs to make an audience believe the impossible. So, she begins a career as a medium by the name of Miss Avila. She wants nothing to do with a detective with the power to destroy the life she's built, but when President Lincoln's youngest son is kidnapped, and the first lady comes to her for help, she can't refuse, even if it means facing Pinkerton agent Carter Forbes, who knows far too much about her already; and possibly falling in love.
