A young British woman, Louise, goes to Afghanistan to do a twelve month voluntary aid programme. She gets close to one of the Muslim volunteers, and he encourages Louise to come to some 'meetings' with him. Louise has been brought up a church going Christian, but she secretly converts to Islam. Louise's year ends, and she comes home. She remains, outwardly, a Christian, but in her heart, she's a Muslim. She is also a sleeper for a terrorist organisation.
On returning home, Louise gets a job in local government. She also marries an ambitious man, who enters Parliament. Louise is called on three times to plant devices for the terrorists she works for. She believes her actions will get her Allah's blessings, but begins to doubt this when, after a night out, Louise attacks her best friend, Millie.
The first twp devices detonate and cause havoc and death. The third device she plants in the master bedroom of Number 10 Downing Street, and this will detonate during a Cabinet Meeting. By this time, Louise wants no more to do with the terrorist group, but she has to plant the third bomb, or her children will get hurt. Just before the third device detonates, Louise informs her security detail, but is too late.
She is arrested, and cooperates fully with the investigation. Louise loses a lot when the third bomb goes off, including her freedom. She neither wants or expects sympathy for her situation. She knows she's done wrong, and can't believe how gullible she's been over the years.
I really enjoyed this story. I really felt sorry for Louise, as her life changed for ever as a result of her actions. She lost so much because of her indoctrination/brainwashing. Even though I felt sorry for her, Louise had broken the law, mistakenly thinking she was furthering the cause of Islam. But, as one two of the characters point out, true Islam is a peaceful faith.
