My Personal Fables [EPUB ebook] 
(Book 2: the Legends of the Mystical Horses)

The Legend of the Horse continues. Seequest
(the Unicorn King) is now living out his days
with his dear friend Princess Helena in
Neptune’s kingdom of Vissen as a glorious
hippocampus (water horse) with a complete
twist in the tale once again, as there are
more mystical and magical creatures being
born that seemed to have become legends
of our time, whom we all know and love in the
present day.
Come and join Seequest once again on his
lifetime adventures.
