I agree that writers like Sproul, Carson and Nash are hard to beat (probably so is the other author, just have not read him)... for Philosophy from a Christian perspective you can look at A Handbook for Christian Philosophy by Bush; Christian Apologetics by Norm Geisler, and he also has a handbook devoted to logic in particular called Come Let Us Reason, co-authored by Brooks; Both And: A Balanced Apologetic by Ron Mayers; Scaling the Secular City by JP Moreland; Classical Apologetics by Sproul, Gerstner and Lindsley; Faith and Reason by Nash, as well as Life's Ultimate Questions, and Worldviews in Conflict are all good apologetic material; Faith and Understanding by Paul Helm; from the Presuppositional camp there is, of course, anything written by Van Til (you can find him on the web), and 2 books devoted to exploring his thought, one by Greg Bahnsen and the other by John Frame, Frame has also written Apologetics to the Glory of God; James White (not of Alpha and Omega) has written critiques of several of the most important modern Christian philosopher/theologians, namely Cornelius Van Til, Francis Schaeffer, Carl Henry, Donald Bloesh and Millard Erickson, in a book called What is Truth? A Comparative Study of the Positions of... (the authors just listed); there is Varieties of Christian Apologetics by Bernard Ramm, oh, and another book from a person symphathetic to Presuppositionalists is Roberty Reymond's The Justification of Knowledge which, like several of the above, deals more specifically with the branch of philosophy called Epistemology;
