Joan nodded politely, but said nothing.

‘I know she’s sad about leaving,’ Leanne said one evening as we sat in the garden listening to the birds while Joan helped her grandparents pack up some of her things. ‘I’m sad about it. I’m not underestimating how big and scary this change is. But kids move all the time – Joan used to live in Liverpool, and she managed the transition to here fine. I know that leaving her dog is a tough one, but she’s only had him a couple of months, and we can get a guinea pig that can live in the garden away from Dad. I’ve said I’ll look into that dog-borrowing scheme once we’re settled.’

‘Sounds great,’ I replied.

Leanne sighed. ‘No it doesn’t, it sounds like I’m kidding myself. After all this, I’m uprooting her from everything she loves and plonking her down in a strange place, with no trees or streams or all the things that she loves. Don’t think for one second that I’m not in bits about it.’

‘That’s not true.’

‘Excuse me?’ Leanne squinted at me sideways. ‘Just because I don’t show her or Mum and Dad how I feel.’

‘It’s not true that you’re taking her away from everything she loves.’ I gave her a nudge. ‘Not only you. She’s gained a family, which was her biggest dream. And besides, they have libraries up north, don’t they?’

She gave a wry laugh. ‘I think Dad’d buy her a whole bookshop if it made her happy.’

‘She will be okay. It might take time, but she’ll get there.’ I could almost believe it for Joan. Whether I’d be okay was a whole other matter. Which was probably what prompted me to keep talking. ‘But if she’s really not, and she’s… she’s not able to be Joan any more, well… this is probably crossing the line, but you know that she’s always welcome to stay here. I mean, for summer holidays or half-term or until I’ve died of old age, whatever works best.’

Leanne twisted around to face me, her movements still slow and careful. ‘Ollie, after everything that you’ve done, there is no line between you and me. Ever. Who knows how much worse this whole thing would have been without you barging your way over that stupid line I’d drawn to keep everyone out. You gave her a home.’ She looked me right in the eye. ‘Thank you. I appreciate the offer, but I’ve spent too much time away from her already, without packing her off here for a holiday. Although,’ she pulled a face, ‘Give it a couple of weeks back with Mum and Dad and I’ll be the one needing a holiday. Perhaps we’ll both come for a break.’

‘The door’s always open.’
