How Algebra Split the December Night [EPUB ebook] 

Believing herself abandoned by her parents, a young girl sets off on a quest to find them and on the way finds herself. Travelling through Russia, Romania, Finland, Sweden and America, her search is aided at different times by her Aunts Aninya, Elena and Katya. On a journey of discovery spanning the early 1900s until the 1920s, set against the backdrop of WW1 and a time of great change, she finally finds herself in Jazz Age New York looking for answers. This is a story of hope and belief in oneself, aided by fate and circumstance.
