Blood knot - Denise Ryan

People hate it when Alyssa says she's innocent. Because they get the nasty feeling she's telling the truth. She's out of jail and desperate to find the mother and sister she never knew. But will they want to know a convicted murderer? And if Alyssa's innocent - who is guilty? Alyssa's brand new sister, Frankie, has troubles of her own. Her happy life abroad is falling apart, her marriage is collapsing and she's just discovered she owes a huge debt she can't pay. A mystery person offers to take over Frankie's debt. Why? Whatever they want, it's got to be worth 100,000.
