Ava Church Garrison, once a force to be reckoned with in the world of finance is now a broken shell of her former self. Ever since her 2 year old son, Noah, was kidnapped 2 years ago, Ava has been teetering on the brink of madness. She dreams of him, hears him calling to her in the night, and even sees him. Although Ava knows it's impossible, she can't help but respond to the cries and the visions. This makes her seem even crazier to everyone that knows her.

Living in a huge old house with only relatives and staff, Ava doesn't know who to trust. Her husband, Wyatt, doesn't seem to be the doting husband he should be. In fact, he might even be having an affair with her psychologist, Evelyn. Her wheel chair bound cousin, Jewel-Anne, is secretive and very odd with obsession of dolls and Elvis Presley music. Of course, she blames Ava for the accident that put her in the wheel chair. Then, there's Khloe, her best friend for years, the woman that also served as Noah's nanny at the time he was kidnapped. Can Ava really trust her, either?

The night that Ava dives into the icy ocean after seeing a vision of Noah doing the same, she's rescued by Austin Dern, a man that Wyatt hired to help out with the animals on the island. Almost instantly, Ava realizes that there's much more to Austin than at first glance. He also looks familiar to her but she can't place why.

As Ava realizes that she's the only person left that truly believes she can find her son, some of her former strength starts to return to her. She begins her own investigation into her son's disappearance. While she's not coming up with a lot of clues, her fuzzy memory of the past slowly begins to come back to her in bits and pieces. Everything is still very murky but she remembers enough to know that someone is trying to drive her mad.

Ava starts to unravel some things that may lead her to Noah but, as she does, people close to her begin turning up murdered. Is someone trying to make Ava seem like a murderer? Or will someone go to any lengths to keep Ava from remembering the past and finding out the secret to what happened to her son that long ago night? Ava finds an unlikely ally in Austin Dern as well as an attraction that she feels she has no business acknowledging.

Lisa Jackson has long been a huge favorite of mine when it comes to authors. YOU DON'T WANT TO KNOW is another in a very long line of nerve jangling, mysterious books that she can proudly lay claim to writing. This one holds some secrets that you're not going to figure out until Ms. Jackson is ready for you to. It's a spooky ride through a house of horrors and one that you'll love every minute of!
