I really like He and I by Gabrielle Bossis. Other people here have mentioned the intro (written by the translator) being new age-y, and since it’s translated from French, the wording has struck me as a bit literal at times, but it really did a good job helping me understand Jesus’ relationship with us on more of a personal level. For background, it’s the writings of a Catholic laywoman in France a bit before and after WWII if I’m not mistaken. Supposedly she heard Jesus’ voice every so often during the day, and would record what He said to her. I’m pretty sure most copies, or at least the parts she wrote, have the Imprimatur. There are various threads about the book on here if you search it.
Honestly, I’ve read most of it so far and it’s really touching. Several parts in particular have actually made me cry, and I don’t do that often. I’m actually pretty sure I’ve posted about the book before. I highly recommend it, just read it with the knowledge that it IS about one person’s individual relationship with Jesus, and that it isn’t doctrinal, though I haven’t found anything inconsistent with the teachings of the Church. Overall, it’s a pretty inspiring read and has brought me a lot of peace.
