The book is written/presented in English and in the language they speak in Balbalan. It's a nice book to add to your shelf of Cordillera literature.
You can get copies of the book from the Mt. Cloud Bookshop in Baguio City.
The book was also recently adapted into a play at the University of the Philippines Baguio. Presented by the Dulaang UP Baguio and Paggawisan Tako Am-in (PAGTA), the play was directed by Markneel Balgos and Eirene June Taclobao. I went to see a showing of the play last March 19. I believe the play is available on the page of Dulaang UP Baguio for those interested in watching the play.
