The hope flower / Joy Dettman.

"Lori and her brothers can survive anything, even their mother" -- cover.

Lori Smyth-Owen isn't your average teenager - as you'd expect from the only girl in a family of twelve. Or they were a family, until their father took his own life to escape his bed-bound wife, too obese to leave her room. But for Lori and the remaining brothers, there is no escape from their volatile, mentally unstable mother. They raise themselves away from the gaze of the authorities, realising that though abandoned, they are now in charge. They can control everything, including their mother's food intake. In time, their mother emerges, after losing two-thirds of her body weight. But does she bring with her the seed of hope for a better future, or will all hell break loose?. -- Publisher's website.
