Charmseeker Sesame Brown's tenth quest for the remaining four magical charms of Karisma takes her to Mermaid Rock, where she must journey beneath the waves to recover the next charm - the dolphin. Charmingly written stories, appealing characters, a beautifully imagined world with its own language - plus a silver charm to add to your bracelet with each book. Collect them all - heart, horseshoe, shell, dolphin, moon, lantern, four leaf clover, snowflake, star, coin, horseshoe, cat and key - and complete the bracelet.
