Dorrance Domain [PDF ebook] 

This charmer geared for younger audiences will draw in even reluctant readers. Fed up with the rat race and hassle of life in the big city, four children and their doting, adventurous grandmother take up residence in an abandoned hotel. Though teamwork, perseverance, trial and error, and some good luck, the scrappy family toughs it out and makes the Dorrance Domain a cozy home.
