Thomas Lane, The Heart of Catholic Spirituality -- Google Books
It is supposed to be from Paulist Press, but I can't find the book on the website.

I don't think the author is the same Thomas Lane as this one, associated with the St. Paul Center for Biblical Theology: Fr. Thomas Lane.

How reliable and trustworthy is this book?

Hmm... Fr Michel de Verteuil's Lectio Divina :: WELCOME and Michel de Verteuil, C.S.Sp. - Lectio Divina.
