Her style is far more effusive than is fashionable, which may make reading her a little harder than it should be.
I don't care much for invoking Mary or relying on departed saints to keep tabs on us. I remain to be persuaded that being a nun is more holy than being an aunt. I'm dubious of the notion of hoping for suffering. There should be suffering aplenty without hoping for it. True, it is one aspect of our relationship with Christ, but IIRC Jesus asked "Take this cup from me."
But her "Little Way" is first and foremost a way of faith, and I kept being reminded of Luther. We are all little, though our tasks may be large.
From time to time I thought she was overstating her suffering, but that's forgivable.
God calls us in different ways, but this little "doctor of the church" is worth reading. Just don't expect showers of roses.
