That’s the one. I have taken a glance at his book (now in its 3rd edition, from a respectable publishing house), and it looks mostly good… But I would suggest using that resource in conjunction with a spiritual director or at least regular confessor to whom your daughter can manifest her distinctively spiritual problems to and receive direct practical guidance. Most any priest will do… But if you can find someone older, who is particularly keen and prudent, that is ideal (as these are normal traits to look for in a director - typically not newly ordained men, for instance, who are not used to holding the “handle-bars” of souls and moving them around).
I have a license in moral theology, for what it’s worth… and have taken a particular interest in this world. I should probably buy that book myself - or write my own!
God bless you,
