Harry Potter and the Summer of Secrets

After the disastrous escape from the Dursleys before his second year, Harry is reluctant to return to Privet Drive for the break between his second and third years. Luckily, Harry has recently discovered a hidden chamber that few have access to, and made friends with a house elf who owes him a favor or two. Hiding in the Chamber of Secrets for the summer with only Dobby, a dead basilisk, a mangey-looking dog he finds, and a portrait that is weirdly interested in mentoring him might be a recipe for disaster, but could also be the best summer Harry's ever had (not that there's much competition really).
