Perfect Sister. The Perfect Series

She raised her sister. She protected her sister. She thought she knew her sister. Meg Simpson was sixteen when her parents died in a highway crash, leaving her to raise twelve-year-old Ann alone. No life insurance. No family. Just two orphaned girls and fourteen years of impossible choices. But Meg kept her promise. Ann never went hungry. Never entered foster care. Never knew what Meg endured to keep them together.
Now Meg is 30, an ICU nurse at County General Hospital, and engaged to pediatrician Benjamin Flint. Ann works in the same hospital as an ER nurse. They're close. They're safe. They've made it. Then Meg finds something that doesn't make sense. A small detail. Easy to dismiss. But Meg is trained to notice what others miss-the vital sign that's slightly off, the symptom that doesn't fit the diagnosis.
And this detail doesn't fit. So she looks closer. Secret meetings. Coordinated schedules. Lies that overlap too perfectly. Her fiancé and her sister, the two people she trusts most, keeping something from her. What starts as curiosity becomes surveillance. Questions become evidence. Doubt becomes certainty. Meg begins to see patterns everywhere-in hospital schedules, phone records, the way they look at each other when they think she's not watching.
She's spent her entire adult life protecting Ann from threats. Now she has to consider: what if the threat is closer than she thought?As Meg's investigation deepens, her carefully controlled life begins to unravel. The nurse who saves lives in the ICU finds herself making choices she never imagined. The sister who sacrificed everything discovers that protection and possession might not be so different after all.
Because Meg learned long ago that the world takes from people like her. Unless they take first. A gripping psychological thriller about obsession, paranoia, and the thin line between love and destruction. Nothing is as it seems, and the people we'd die for might be the ones we can't trust.
