It has been a long, hard winter, and the Gypsies are glad to be leaving Lord Levin's mountains for the sunny plains of Lord Kaybale's lands. But that means time is running out for Heart. The old stories say that Castle Avamir is higher than the clouds, deep in a valley, under the stars, and over the moon. It makes no sense -- but if Heart can't solve the riddle, she might never find a safe haven for her beloved unicorns.

About the author

Kathleen Duey

Kathleen Duey grew up in Colorado. She loved riding her horses, hiking, being in the mountains. Reading was always important to her. Writing became a fascination early in her life. In the fourth grade, Kathleen began writing stories and told everyone who would listen that she was going to be an author. Then she did nothing about it until she was 35 years old. Writing was her passion and her dream-come-true.

Kathleen died of cardiac arrest at her home in Fallbrook, California. She was 69. She had struggled with dementia in her latter years which prevented her from completing her Skin Hunger trilogy.

The threads that bind tighten, but what does it mean. Will Heart ever find out? This one doesn’t solve that mystery. However there are some secrets, or at least parts of them, revealed.

Overall this book is well written and entertaining. Not exactly the best in the series, but definitely one of the better. It is time to see the beginning of the end of the story, the setup at least.

„Тайната на еднорога“ е поредица от 8 илюстровани детски романа, които се четат на един дъх. Сюжетът разказва за малката Харт Авамир, сираче, отгледано от Саймън Прат – груб селянин, който я е открил преди години край реката. Харт няма никакви спомени преди този ден. При все, че е дал подслон на момичето, Саймън съвсем не е обичлива бащинска фигура. Харт е помощник, полезна работна ръка, но не и дъщеря. Отначало Саймън дори не е дал име на детето. Нарича я просто „момиче“, докато местната лечителка, Рут Оукс, не й дава име. Харт мечтае за семейство, да разбере кои са родителите й… Единственото, което знае за тях е, че преди да я оставят край реката те са я повили в красиво одеяло със избродирани сребърни еднорози. Уви, Саймън отдавна го е продал… Прочетете повече на "Книжни Криле": https://knijnikrile.wordpress.com/202...

Heart helps her gypsy friends out of a sticky spot then sets off with one of her unicorns, Moonsilver to find the location of the titular structure. They encounter unexpected guidance from another young girl, travel into the mountains and ultimately find the long-sought fortress. Nary a soul remains but one elder gentlemen who is ushered out by an antagonistic presence, forcing Heart to follow stealthily behind in order to seek answers as to the whereabouts of her family whose presence should certainly be seen in their castle.

My favorite part is when she gets a small silver flower that weaves itself into the silver threads that she gets in the previous books.

Cute feels like some progress but this series would probably have been a lot more fun and fulfilling as a stand-alone novel

I liked that it had secrets. I like that it had suspenseful parts where she might get caught with her unicorn. There were some close calls. It's neat because she is trying to find her parents and plus where to find where her unicorn will be safe.
