"Thrilling stories with plenty of horses plus a measure of mystery and suspense."
--Horse and Pony Magazine

When Ellie and Tara return to Garland House they find the Bartons embarking on a new project at their family estate. Jonah and Ricky's parents are now offering working vacations to families, including courses on organic gardening for parents, and horseback riding lessons for the kids. Ellie and Tara think this sounds like fun to help out with until they meet the visitors! Not only is one visiting boy strangely obsessed with Ellie, making Jonah crazy, but one of the guests thinks there's a ghost. But the old house may, indeed, be haunted--Ellie has felt it, too. Is the reclusive previous owner, Silas, trying to drive the guests away from beyond the grave? Ellie and Jonah plan to find out, but their sleuthing isn't popular among the paying guests. Meanwhile, Jonah has shown Ellie a strange old portrait they found in the house--a portrait containing a horse that looks just like Aslan! Rumor has it that a valuable object is hidden in Garland House. It can't possibly be this strange portrait. But when Ellie puts two and two together, she and Asland must once again brave great danger to solve the mystery.
