Rosie Lewis - Betrayed: The heartbreaking true story of a struggle to escape a cruel life defined by family honour

Do you think shell be like Phoebe was when she first came? my son Jamie called out from his bedroom.

I couldnt help but smile at the hesitancy in his tone as I swept from room to room, checking there were fresh towels in the bathroom and grabbing a floral duvet set from the airing cupboard. Nine-year-old Phoebe had stayed with us for almost a year before moving on to a long-term carer. The friendly, kind and bubbly girl we said goodbye to was unrecognisable from the angry whirlwind we had first met. Our house seemed so much emptier without her presence and, despite her leaving months earlier and other children staying with us meanwhile, we still missed her. But the first few weeks of Phoebes stay had been challenging for all of us, especially so for Jamie.

From the moment she arrived Phoebe had fixated on him so that, whenever she was confused or upset, Jamie would be the one who got a wet finger shoved into his ear or a plate thrown at him. As she settled and learnt to trust us we witnessed some dramatic changes in her behaviour, so much so that our motivation to foster had grown even stronger, but the traumatic start had left Jamie chary of new arrivals.

No, I doubt it, I said, though my words sounded hollow. I actually had no idea what Zadie Hassan would be like. In a hurried telephone conversation with her social worker late that afternoon, I had been told that the 13-year-old was from a Muslim family who had never come to the attention of social services before, and so information was sketchy. Of Asian heritage, Zadie had been found by two patrolling police officers early that morning, sheltering in a shop doorway in a central northern shopping centre. Apparently she had pleaded with officers not to take her home, begging as if her life depended on it. She had seemed so genuinely terrified that the officers took her straight to the police station and alerted social services.

At 13, Zadie was outside of our approved age range, but she had spent most of the day waiting at the local authority offices, listening as social workers phoned agency after agency, trying to match her with Muslim foster carers. By the time the decision was reached to settle her with a white British family it was almost 5 p.m. and the poor girl was exhausted. Strictly speaking, our family was only approved to take children from 0 to 11, leaving a gap of at least two years between any child coming into our home and my own youngest, Jamie, who was just 13. But when an ideal match isnt possible and a child urgently needs a warm bed to sleep in, social workers are usually prepared to bend the rules.

A gap of two years is recommended between looked-after and birth children so that the family dynamics are roughly unchanged. If disrupted, resentment against the foster child can build to a point where the placement breaks down. Some fostered children have been so badly abused in their own homes that they find it difficult to witness the positive environment when they arrive in a foster home and seek to sabotage the relationships between family members, so its important to maintain the original pecking order.

Preparing children for family life when they have had little experience of boundaries or parental discipline takes time and patience. Even getting them to sit at the table at meal times can seem like an insurmountable task, in the beginning. I wondered whether we would experience any behavioural issues with Zadie. If so, we would have to brace ourselves to get through the first few weeks while she adjusted to our house rules and boundaries.
