A Princess of Last Resort [EPUB ebook] 

With the  elflands in flames  and the royal family silenced, a distant heir must flee from murderous invaders. Will  Sarah  and her half brother  Granite  survive the frigid wilderness and find the allies that they need to fight back?

Sarah, a half elf mage attending the Arcane University and very distant heir to the throne of Civilia, thought that this was going to be a nice walk in the woods. She had dragged along her older half brother Granite,  a half orc journeyman ranger, so that he could help her to collect some material components for the new school year.

Neither of the Blackstaff siblings expected their little trip to be interrupted by  fire raining down from the sky . And they certainly had no clue that a ragtag mercenary army would use this natural disaster as an opportunity to invade the sovereignty of the northern elves. In desperation, they leap through an unstable portal and find themselves ill prepared for the snowy mountains that surround them.

Now the clever young mage and her fiercely loyal brother not only have to  survive , but they also need to  find new allies  that can help answer the questions that haunt them: Are their parents still alive? Why can nobody reach the elven royal family? Was the firestorm a natural event, or something far more sinister? Finally,  who are these invaders, and what do they want with the Blackstaff siblings?
