A free graded reader with 80 short stories set in 雾河镇, a small town where an old radio starts picking up a strange signal. Unlike most graded readers, the stories form one continuous mystery, so there's a reason to keep reading. Each story gets harder as the plot moves on:

• HSK 1: 8 stories
• HSK 2: 12 stories
• HSK 3: 16 stories
• HSK 4: 20 stories
• HSK 5: 24 stories

Each story takes a few minutes and comes with a vocabulary list (pinyin and definitions), grammar notes and comprehension questions. It runs in the browser, with no account or payment needed.

Made by the developer of Zhenzhu, a Mac reading app. The stories are free and don't require the app.
