Systematic Theology: A Pentecostal Perspective, edited by Stanley M. Horton and published by Logion Press/Gospel Publishing House, is a good overview of beliefs of the Assemblies of God and similar Pentecostal groups.
Anthony D. Palma’s The Holy Spirit: A Pentecostal Perspective lays out a detailed Pentecostal pneumatology.
Two works by Pentecostal theologian Roger Stronstad are important defenses of Pentecostal pneumatology, especially their reading of Acts: The Charismatic Theology of St. Luke and The Prophethood of All Believers.
Roger E. Olson’s Arminian Theology: Myth and Realities seems to be a nice resource for understanding the Arminian/Calvinist divide among non-Lutheran Protestants.
The Lord’s Supper: Five Views, edited by Gordon T. Smith, is a nice volume. A Roman Catholic, Lutheran, Reformed, Baptist, and Pentecostal theologian each contributes a chapter explaining his own traditions understanding of the Eucharist. Then the other contributors write responses.
Wayne Grudem has written a really nice and comprehensive systematic theology from a charismatic Reformed perspective: Systematic Theology: An Introduction to Biblical Doctrine.
Finally, this is not a theological work but rather a historical work. George Marsden’s Understanding Fundamentalism and Evangelicalism.
