These are from a series I loved as a teenager about the several sets of twins who have special powers. They are pretty good and I would recommend if you are stuck for a book.
The first is from the very start. Just when Rachel and Adam think they are safe, Laura has a not so pleasant surprise for them. From the helicopter, they are whisked away from their mother, Kate, who is led away by Laura and basically institutionalised.
The second is from when the twins wake up. They had been kept sedated for days then woke up in rooms that were identical to their own, but were in a strange research facility. Rachel finds Adam’s room, but when Laura walks in, she loses her temper, throwing herself at Laura. When she see’s that Laura doesn’t want to hurt her, she stops fighting, and allows Laura to explain their situation.
The final one is set after the twins escape the HOPE facility. Kate’s drugs have been withdrawn, but she is still unstable. Laura tries to get Kate to talk to her, to get her to trust her, but Kate is beyond reasoning. After telling Laura that if any harm befalls her kids, Kate would kill her, Kate throws her coffee in Laura’s face.
