I Like You Just Fine When You're Not Around / Garvin, Ann

 Everything is falling apart in psychologist Tig Monahan's life. Her mother's dementia is wearing her out; her boyfriend takes off for Hawaii without her; and her sister inexplicably disappears, leaving her newborn behind.
When a therapy session goes horribly wrong, Tig finds herself unemployed and part of the sandwich generation trying to take care of everyone and failing miserably. Just when she thinks she can redefine herself on the radio as an arbiter of fairness, she discovers a family secret that nobody saw coming.

It will take everything plus a sense of humor to see her way clear to a better life, but none of that will happen if she can't let go of her past.
