Unfinished Business by Clare Osongco

In this funny, warmly chaotic novel, a floundering office worker discovers her mother's ghost is trapped in the company Slack server, and must free her by resolving her own troubled love life.

A few months ago, Ruby Ocampo’s mother, Adela, died at her desk at work. Now, lost and driven by a misplaced sense of obligation, Ruby’s taken a job at the megacorporation where Adela worked for decades—and, to her horror, she discovers her mother’s ghost is trapped in the company Slack.

Ruby has never lived up to her mother’s expectations in life, but to set her free, she’ll have to resolve Adela’s unfinished business. She makes a list of all the ways she could live more like her mother would have wanted, covering everything from her stunted career to her love life (#5 on the list: date someone in a higher tax bracket!). Soon her quest to free Adela gets Ruby entangled with two men at the office who might be able to help: the estranged childhood friend her mom never approved of—who's the only one she can confide in about this supernatural crisis—and the hot but vaguely sinister junior executive who's been paying her a confusing amount of attention.

In order to give her mom a chance at the afterlife, Ruby must address her shortcomings one by one—and reevaluate her inherited ideas about love, work, and what’s truly important along the way.
