Uchenna's Apples

In a new short novel by Diane Duane, three suburban Dublin teens are lured into mystery in the mists of Ireland...
Uchenna O'Connor lives a life like that of any other Dublin schoolgirl... until the horses arrive.
The unexplained appearance of a little herd of "tinker ponies" that no one will claim causes no particular stir among adults in the purpose-built suburb of Adamstown... but there are others who notice. Uchenna starts feeling responsible for the ponies that have suddenly turned up on just the other side of the wall separating her suburban home from the fields around Adamstown.
Her growing concern for the hungry and seemingly abandoned horses leads Uchenna into hatching a benevolent plot to secretly take care of them, while she tries to discover who's brought them to her doorstep and why. But Uchenna little realizes the complications that will ensue when she draws two others into her plans: her best friend Emer -- an American transplant with a taste for rocking the boat -- and young Jimmy Garrity, a Traveler boy with a yen for higher math and a stubborn streak that drives him to try to beat the odds against his acceptance by "settled" people.
Together the three of them find themselves enmeshed in trouble in the neighborhood, at school, and even with the police, before the strange unseasonable autumn mist lifts enough for them to have a chance of discovering the truth behind the puzzle. But will the fragile new friendship that's growing in the mist survive the pressures and demands of the adults trying to pull them apart?...
