Thanks to Netgalley and the publisher for an ARC of this book. I have chosen to write this honest review voluntarily and it reflects my personal opinion.
This book is promoted as a story of twins born in England in the early 1900s and then separated. They lead very separate lives, especially once Tommy becomes involved in the Home Child programme.
The story is interesting, and overall it is credible. However the book is written with American spellings throughout (it is supposed to be set in England for most of the story) and frequent poor punctuation which is so distracting it spoils the flow of the tale. There are some major issues with credibility: a nurse puts a tea tray on a dirty hospital floor (Florence Nightingale would turn in her grave), being sent home from hospital only 5 days after suffering a broken jaw (when eating and drinking would still be so difficult there would be issues with nourishment), and 21st birthdays were coming-of-age celebrations, Billy would not have been given anything special for his 18th birthday. The narrative style is odd, with changes back and forth along a timeline, the language is frequently stilted and unnatural, and there are some unrealistic events - Billy waited several weeks for Claire to tell him what happened about the stabbing, this is completely unbelievable.
It seems that this book has been used as a vehicle for criticism of the Home Child programme and I found the history interesting. However, it would have been better if the English parts of the story had been researched better to provide a more realistic, balanced story so I have given it an average rating.

The book centres on twin baby boys separated at birth due to their controlling grandfather and society of that time. As they each go about their lives, Billy living with his mother and Tommy moving through the care system (orphanages as was then) without how either knowing of the other.
Billy goes off to fight for his country, returning a broken man with secrets to hide.
Tommy becomes part of the Home Chidren Scheme getting sent overseas to Canada. Not all the children have good experiences when they get there, being axed as no more than slaves.

I enjoyed the informative parts, never having heard of the child scheme before.
