The blurb clearly states that you should not read this until you have read The Other Son. I will reiterate that here, and also advise you also stop reading reviews for this bonus extra if you haven't read the main book as these too may contain spoilers.
Still here... Right. So, you've read The Other Son and, if you're like me, you really want to know what happened next... Especially with Alice and her relationships with both her sons, her husband and her new tolerance/love of cats! We pick up the action coming up to Christmas. Alice has popped back to the UK to sort some stuff out and we glimpse what happens to her there. Back in France and Matt and Bruno are plotting. With Alice due to return to France for the holidays they set wheels in motion for a big surprise for her. But will she be thrilled or mortified? It's make or break time...!
I actually chose to listen to the wonderful Imogen Church narrate this book, perfect length for a bus trip / shopping in town, and I was held rapt by her wonderful interpretation of the characters that I had already connected to when I read the main book. Sometimes my mind wanders off when I listen when out and about but the story really held my attention nicely throughout. Mainly cos after I cottoned on to what was about to happen, I really wanted to know how it would all go. And... well, no spoilers here!
If you loved The Other Son and want to know what happens next as you really weren't ready to let the characters go, then this is a really great follow up. I do wish more authors would do this. And I also hope that Mr Alexander returns to these characters again in the future. Love them all!
