Of Lies and Earls by Sadie Bosque

Jacob Caldwell is many things—a botanist, an entomologist, an industrialist, and, if he’s being honest, a complete disaster of a guardian. He barely remembers to eat, let alone raise the three children suddenly thrust into his care. What he needs is a housekeeper who is competent, invisible, and entirely uninteresting.
Honoria Hartwell is none of those things. What she is, however, is a liar. Hiding in plain sight as a housekeeper is the safest way to escape her horrid past. But when the lure of her old life proves too irresistible, she takes one reckless risk and… finds herself in the arms of her employer.
Now, Honoria is trapped between two lives and drowning in a web of lies. When her past finally catches up with her, will the man she has started to love come to her rescue or abandon her to her fate?
