Anything for You by Jessie Gussman

After the circus she works for goes bankrupt, Jillian Powell takes advantage of a dubious family connection.
The little farm in Pennsylvania that belongs to her “cousin” is a safe haven for Jillian, and she’s sure no one will ever uncover the incriminating truth she’s hiding…
…until an elephant shows up on her doorstep.
By-the-book animal control officer, McKoy Rodning, is thrown for a loop when an elephant crashes his best friend’s wedding.
He’s even more confused when the exotic Jillian evades all of his questions about permits and regulations. All he knows for sure is that she’s emphatic about reuniting the depressed animal with her elephant sister.
McCoy finds himself uncharacteristically bending the rules to help Jillian, risking both his job and upcoming promotion. When her secret is exposed, he’s faced with following the rules or following his heart.
