The Ex Who Glowed in the Dark (Charley's Ghost) by Sally Carlene Berneathy

Amanda was divorcing her lying, cheating husband
Charley when he was murdered. Now she’s stuck with his ghost and finds herself
entangled in a kidnapping. The younger brother of her assistant, Dawson, has
been kidnapped.

Strange,
though, that Dawson's never mentioned a brother, and when an e-mail arrives
demanding a ransom for the boy, it's not the usual large sum of money in
unmarked bills they want, it's computer code. WTF?

Do the kidnappers really exist? Is Dawson’s
brother only an Avatar from one of his computer games? Will Amanda ever get rid
of Charley? Will she give up her Coke for a Pepsi? Will Global Warming melt her
Magnum Double Chocolate ice cream bar?

Okay, you need to test that last question for
yourself, but the answers to everything else are in this book!
