What to expect
A BRAND-NEW heart-pounding psychological thriller from international bestseller Jill Childs, perfect for fans of Lisa Jewell, KL Slater and Freida McFadden 💫🏠😮
A hidden bond. A deadly betrayal…
When Arabella learns she was adopted, her perfect life begins to crack. A lost birth mother, an unknown twin, and rising jealousy pull her into a spiral of obsession.
Helen, starting over in a quiet Cornish town, meets Arabella by chance. Their connection is instant – two fragile women offering each other help. But when Arabella vanishes to seek support for her unravelling mind, Helen is drawn into her home, her family - and her life...
As sinister events escalate, Helen begins to doubt everything: Arabella’s mysterious illness, her too-charming husband, and the secrets locked behind closed doors.
By the time she uncovers the truth, it may be too late.
Dark, twisty, and addictive, Good Sister, Bad Sister is a gripping psychological thriller about sisterhood, obsession, and how far we’ll go to rewrite the past.
