It’s 1918, and a mysterious telegram catapults Lady Mina Tretheway into a wartime mission for her country and her heart.

Mina Tretheway receives an urgent telegram at her boarding school. She fears the worst as the War rages on. Mina discovers that the telegram from her father is in code and tells her to come home. Upon her return home to Hallington Manor, Mina finds an old friend- Lord Andrew Graham and an American- Lucas Mueller. They need Mina's help in order to complete a dangerous mission in Germany. Before Andrew and Lucas set off on their mission, an accident happens and Andrew is incapacitated. Mina is determined to help Lucas see the mission through, although Lucas believes she is too frail and spoiled. Before Lucas can convince Mina to return home, they are thrown together to complete the mission and survive.

All Is Fair is an exciting and adventurous Young Adult novel set during World War I. Mina's character was charming and invigorating as a young woman good with codes, ciphers and languages. The writing did have a slow build in the beginning, but did build up the dreadful feeling of wartime and the suspense that not all was right at Hallington Manor. About halfway through, when Mina became part of the mission with Luke, the pace picked up and I couldn't stop reading. Their spy mission was intriguing and added a dash of sweet romance. I liked that she proved her worth during the mission as a woman and because she was a woman. Through Mina's and Lucas' eyes we see bits of the harsh realities of war and also learn about the Dame Blanche Resistance movement of France and Belgium which was primarily comprised of female members. Overall, an exhilarating young adult spy thriller.
