Tellraw doesn't run and produces error message

Using 15w43c, the latest 1.9 Snapshot, I'm using tellraw and it gives me a error no matter what I do. My command is: /tellraw @a "To all who are wandering lost in the dark..." But instead of doing what it's supposed to, and display "To all who are wandering lost in the dark..." it gives me the following error message: "[19:09:07] Invalid json: malformed JSON at line 1 column 2"
Thanks in advance, I unlike others love every bit of 1.9, and am excited for it's release. Thank you so much, -starcatcher77
