hibernate - HibernateCriteriaBuilder Grails

Question

I have a domain

Author{
   String name
   String AuthorId
   hasMany = [books:Book]
}

and

Book{
   String title
   String publisher
   belongsTo = [author:Author]
}

The only input I can have is AuthorId. With the use of this value how to obtain the records for domain Book using HibernetCriteriaBuilder eq(propertyName, propertyValue)

Thank you!!!
