// Create the query
IQuery<Human> query = new Query<Human>("humans") // set the name of the query
 .AddArguments(new { id = "uE78f5hq" }) // add query arguments
 .AddField(h => h.FirstName) // add firstName field
 .AddField(h => h.LastName) // add lastName field
 .AddField( // add a sub-object field
 h => h.HomePlanet, // set the name of the field
 sq => sq /// build the sub-query
 .AddField(p => p.Name)
 )
 .AddField<human>( // add a sub-list field
 h => h.Friends,
 sq => sq
 .AddField(f => f.FirstName)
 .AddField(f => f.LastName)
 );

// FirstName
// LastName
// HomePlanet {
// Name
// }
// Friends {
