Bump Up the Oxygen - Mary Jordan Nixon

... Miranda Blight's fall into brokenness and her bizarre struggle to rise again ...the humor and romance are as riveting as the suspense...

Miranda Blight's life is falling apart: her husband's a jerk, her handcrafted dolls don't sell, her body rebels. Following surgery, she butts heads with Mrs. Vic, her former evil nursing instructor, who continues to boss and manipulate, despite paralysis.

Pain and post-op drugs befuddle Miranda; she cannot escape Mrs. Vic's diabolical schemes to catch the woman's son-in-law, who may have killed his wife.

The further Miranda falls into the secrets and dangers of Mrs. Vic's life, the more she is challenged by quirky evidence, odd weapons and a confusing, handcontrolled wheelchair van; when Miranda is forced to drive this vehicle to the ends of Mrs. Vic's insane world, her own life splits wide open.
