Just last year, the Association of American Publishers ranked Children's/Young Adult books as the single fastest-growing publishing category. Which is why we were only a little surprised to see the tremendous response that came in for this summer's Best-Ever Teen Fiction poll.

A time for medical teams in which they could act without risk for a heart attack or permanent brain injury. The first tests in animals are completed with a success. They say that doctors are able to inject this liquid into a vein restoring blood oxygen levels , giving the animals who needed those extra minutes .

Tips & Lessons > Fragmenting: A Quilt Design from a Single Block I often use fragmenting when designing quilts. The concept of fragmenting a traditional patchwork block is not new. It has been used for centuries with the traditional Lone Star design.
