The Oblivious Girl's Handbook. The Handbook Series, #2

Being oblivious to all the signs that your life is about to fall apart doesn't stop it from happening to Sara Taylor. Alone except for the Siamese cat her boyfriend-ex-boyfriend-Joseph left behind to teach her a lesson, Sara has no clue how to survive on her own. She hasn't handled her own bills in years, can't meet a deadline without someone else programming alarms into her phone, and is constantly either losing important things or getting herself hopelessly lost.
Sara has no idea how she's supposed to move out of her university apartment and start her first real job without someone there to hold her hand. Although she knows her new friend Monroe would step in to help, she's not about to call him after having thrown him out of her apartment when his suspicions about Joseph prove true and Sara is left angry and mortified. It doesn't take long before she is desperate to lean on someone else's strength, even for just a few minutes, as real life begins to overwhelm her.
Pride forces her to either sink or swim, even when sinking seems the most likely outcome.
