Prisoner of Ice and Snow is about a girl called Valor who is determined to break her sister out of prison - from the inside. After she commits a crime and is sent to prison, she couldn't be happier. Now she just has to follow her plan, and Valor and her sister Sasha will be free in no time... Or so she thinks.

This story is suitable for younger teenagers. Prisoner of Ice and Snow is a fast paced story, set in a fictional world. There is no romance, but I didn't miss it. The relationship between Valor and Sasha is well done, and there is some great supporting characters as well.

This story was very entertaining and had me hooked from the start. I'll be keeping my eye out for a sequel after that ending too!

This is a highly enjoyable children's adventure with classic ingredients: fictional countries and royal families; palace, prison, and dungeon; and themes of loyalty and betrayal.

Valor cannot rest until and unless she saves her twin sister Sasha, who has been found guilty of stealing a valuable music box that was to seal the treaty of alliance between Demidova and neighbouring country Magadanskya. Sasha has been sentenced to a harsh children's gaol that nobody has escaped from in 300 years but Valor is determined to join her sister and break them out of prison. Who can Valor trust to help in her quest?

This book is really good in its treatment of friendship, trust and loyalty and how these elements drive Valor to persevere and not give up. I admire how the writer Ruth Lauren illustrates the dangers in the story by examples of extreme heat and cold, from scalding hot water in a kitchen to becoming perilously cold in a cell of ice.

I recommend this story and I am looking forward to the second book in the series.

I received this ebook free from Net Galley and publisher Bloomsbury.
