Early Syriac Theology and Introduction to Eastern Christian Spirituality: The Syriac Tradition are two of the finest introductions to the Maronite-Syriac tradition out there. I’d also recommend simply going straight to the sources - read Mor Ephrem, Jacob of Sarug, Isaac (the Syrian) of Nineveh, The Book of Steps, Philoxenus of Mabbug, etc. They’re all wonderful.
I’ve read Captivated by Your Teachings, and portions of it I’ve read multiple times. I’m not a fan, honestly, and I know several Maronites much more knowledgeable than myself who are similarly not fans. To my recollection, the author hardly ever references the Syriac Fathers, and when he does it’s usually just Theodore of Mopsuestia (a controversial figure). Otherwise he mostly references the Catechism of the Catholic Church, the documents of Vatican II, and the Maronite liturgical texts. Chorbishop Seely Beggiani’s approach in Early Syriac Theology is much better in that he references our liturgical texts along with the Syriac Fathers (particularly Ephrem and Jacob of Sarug).
Christ Our Pascha is a Byzantine book and will give you an excellent perspective on the Byzantine tradition. I have a copy of it myself for work purposes. But it’s best to keep in mind that the Byzantine tradition is not equivalent to the Eastern tradition (in much the same way that the Roman tradition is not equivalent to the Catholic tradition). The Syriac tradition is unique and distinct from the Byzantine tradition, so if it’s the Maronite-Syriac tradition that you are particularly interested in, then you’re going to want to stick with Maronite-Syriac sources.
I hope that’s helpful.
