Written books with JSON don't get created correctly (no color and styles)

I already saw screenshots where this bug weren't, but for me the the colors and styles aren't visible:

/give @p written_book 1 0 {title:"Getting around",author:"Searge",pages:["{text:\"Welcome, \",extra:[
{selector:\"@p\",color:red}
,
{text:\"\n\nthis is your list of destinations:\n\n\"}
,{text:\"1. \",color:orange,extra:[
{text:\"Spawn\",color:dark_green,bold:true}
],hoverEvent:

{text:\"\n\"}
