There’s nothing on the book proclaiming it to be part of a series, but I kinda got the sense it was, so I did an online search and did indeed find many Tashi books by the same author.  I think the reason I suspected it was part of a series was that there wasn’t really any character development, and it read kind of like we were already supposed to know who Tashi was.  If you’ve got students who already know and like this character, this might be a good addition to your collection, but as a stand-alone book I didn’t find it very strong. One year when the rains don’t come as usual, Tashi sets off to try to find the dragon who causes them and ask him why; he meets a tiger along the way who points him in the right direction, explaining that there’s a young dragon who hasn’t learned to control his powers yet; upon finding the young dragon, Tashi discovers he’s sad and lonely because he ate his sister and his mother’s been put to sleep by a demon and won’t wake up; Tashi convinces the young dragon to sing to comfort himself, which wakes Mom, who explains how to unswallow Sis and agrees to send the rains, so Tashi was a hero.  I thought it was rather long and rambly, but maybe I would have appreciated it more if I know more about the main character.
