Master of the Hall (Eden Hall #4) by Veronica Heley

Eden Hall, the ancient English stately home, has brought Araminta 'Minty' Sands more joy---and heartache--- than she could ever have imagined. She's worked hard to keep it open to the public; but, exhausted from looking after the twins, Minty has no energy to maintain the Hall as she once did. Worn-out and fearing another trouble-filled pregnancy, she's also pushed her husband, Patrick, away physically and emotionally. And now her old enemy has returned: Judith Kent, known worldwide as amoral rock star Maxine. Claiming to be reformed, Judith begs Minty for a job. Against her better judgment, Minty agrees. Then, with Patrick in Brussels on urgent business, mysterious 'accidents' begin to happen, endangering both Minty and her twins. When a horrifying secret surfaces---one that, if made public, could destroy the hall and everything she has worked for---Minty realizes time is running out. Has Judith really turned her life over to God, or is she plotting to take over everything Minty has---including Patrick?
