'search' returns an array, so in scalar context this will put the array 
size into '$author' not what you want. Use either
my ($author) = $c->model('MyAppDB::Author')->search({name => 
$amazonauthor});

or

my $author = $c->model('MyAppDB::Author')->search({name => 
$amazonauthor})->first;

I think this should be '$author->id'
