How to Train a Viscount by Bianca Blythe

Do you want to be a viscount?
Adam is shocked when his employer unexpectedly becomes a viscount, but he is more shocked when his employer is murdered. When the killer spots Adam, there’s only one thing Adam can do: flee. Fortunately, he has his employer’s papers with him, including a boarding ticket to England. Less fortunately, everyone is eager to introduce him as a new viscount. If Adam is going to avoid imprisonment for impersonating a nobleman, he needs to convince people that he actually is one. The only problem… He doesn’t know anything about being an aristocrat.

She’ll make a viscount out of you.

Training Adam was supposed to be a diversion, but it was never supposed to involve her heart.
