Blood Ties. Book 2. Golden Lily

Sydney managed to regain the trust of her fellow alchemists, but for how long? One misstep, and she could be suspected of getting too close to her "wards" — the vampires. After all, they really do get along well. Together,... Sydney, the Moroi, and the dampirs conduct experiments with rare and mysterious spirit magic, and even the slacker Adrian is trying to pull himself together. But soon all the heroes will have to acknowledge that in this world, where vampires are real, other myths can come to life as well.

The second book of the series "Blood Ties", expanding the legendary universe of "Vampire Academy", in a convenient classic pocket format.
